7 are the traits of a hacham (Avot 5:9) (also of a golem, but let's be positive here)
Sevens by Ari Lesser
Passover extends seven days my friends
And from the night after the first day ends
We count seven times seven days till Shavuot
Refining our souls with the seven Spheriot
We go through Tiferet, Malchut, Yesod
Chesed, Gevurah, Netzach, and Hod
We’re not tzaddiks but after seven weeks
We’re ready to receive the words G-d speaks
In the Holy of Holies the High Priest whips
Seven drips of blood from his fingertips
In the seventh month we atone for our sins
In the seventh month when the year begins
In the seventh month sound the Shofar blast
After seven, seven-year cycles have passed
Throughout the land we declare Jubilee
Every debt is forgiven every slave goes free
Every seventh year is Shabbat for the land
In the seventh year we leave it in G-d’s hand
No one reaps, and no one sows
In the seventh year we just eat what grows
There’s barley and wheat, figs and dates
Pomegranates and olives and grapes
The seven species of the holy land
Growing as abundant as the beach has sand
Seven Brachas all seven days of the celebration
Of a wedding when a man and wife begin to have relations
But during menstruation there’s no cohabitation
They keep a seven-day period of separation
Uncircumcised first seven days that we’re born
Sit shiva in the house seven days when we mourn
Tefillin wraps seven straps round the arm when we pray
Every morning of the week except the seventh day
And when we dwell in the sukkah seven days of Sukkot
On the seventh day there’s seven hoshanot
With seven of the four species we make a line
As we circle the bimah seven times
In the seventh month after the year’s head
Seven days of Pesach we eat no bread
On all seven we’d to bring a ram, and a goat
Two bulls, and seven lambs for the Korbanot
Passover extends seven days my friends And from the night after the first day ends We count seven times seven days till Shavuot Refining our souls with the seven Spheriot We go through Tiferet, Malchut, Yesod Chesed, Gevurah, Netzach, and Hod We’re not tzaddiks but after seven weeks We’re ready to receive the words G-d speaks On the seventh day rise up to the Torah Read one of seven aliyahs from the Parshah Bereshit Bara Elokim, the first Line in the Torah is a seven word verse G-d created to earth and the heavens Worked six days and was done on the seventh So the seventh day is the day of rest The seventh day G-d blessed with Holiness He made Adam and Chava and she was the mother Of Cayin and Hevel who was killed by his brother But G-d didn’t punish Cayin for seven generations So violence and robbery spread through creation Til G-d said to Noach, “In seven days The waters of the flood will begin to raise So get seven other people, and bring at least Seven pairs of each kosher bird and beast.” So Noach got seven male and seven female Of each clean creature on the Ark set sail Til the seventh month, when the waters dropped And the ark came to rest on the mountain top Let the raven fly, seven days went by Sent the dove, she came back cause nothing was dry Waited seven days at the end of the week Sent the dove, she returned olive branch in beak He still wasn’t sure so he waited seven more Sent the dove buts she didn’t come back like before Cause the flood was over, for Noah G-d showed A Sign in the cloud, seven color rainbow Then he gave seven Noachide laws to be done By the seventy nations who come from Noach’s sons But there was evil in the seven nations of Canaan So G-d swore to give their land to Avraham Who lived in Beer Sheva that was the well spring Where he gave seven sheep to the Philistine king And Sarah was Avraham’s beautiful wife One hundred twenty seven were the years of her life There’s seven generations from Avraham to Moses I’ll keep the story short most everybody knows this Sarah bore Yitzchak to Avraham Yitzchak begot Yaakov, who ran to Aram For seven years Yaakov work like hell For his uncle Lavan, trying to marry Rachel But the night he wed, he got tricked instead Woke up and found Leah, was laying in his bed Seven kids came through Leah, that’s true But Yaakov knew he had to have Rachel too So after seven days another wedding was on But he had to work seven more years for Lavan And when his son Yoseph was just seventeen He got sold as a slave down to Mitzrayim He was sitting in prison when Pharaoh had a dream And nobody in Egypt knew what it could mean He dreamt seven cows all healthy and fat Emerged from the river and behold after that There came seven cows looking ugly and cursed And the second seven ate the seven cows that were first And he dreamed seven ears of grain all stood On a single stalk, they were full and good But then grew seven thin ears withered by the wind The first seven got swallowed by the seven that were thin Yosef said, “Pharaoh, your dream about the grain And your dream about the cows, are one and the same To me it’s clear that the seven full ears And the seven fat cows are seven good years The seven thin ears and the seven cows that were lean Are seven bad years, and the meaning of your dream Is that seven years of plenty will come and get swallowed By seven years of famine that immediately follow.” Then Pharaoh repaid Yoseph, who had saved Egypt, making his family their slaves But his wise men told him they saw in the stars The Moshe would be born on the seventh of Adar They were right, Moshe started a fight Killed and Egyptian then he had to take flight Married one of seven daughters of Yitro Before he told Pharaoh, “Let my people go” Seven plagues brought Egypt down on it’s knee And like a low blow, Bo, there came the last three G-d split the sea and we walked seven weeks Up to mount Sinai where we heard G-d speak Passover extends seven days my friends And from night after the first day ends We count seven times seven days till Shavuot Refining our souls with the seven Spheriot We go through Tiferet, Malchut, Yesod Chesed, Gevurah, Netzach, and Hod We’re not tzaddiks but after seven weeks We’re ready to receive the words G-d speaks On the seventh day G-d called and allowed Moshe to ascend to midst of the cloud HASHEM let him stand in the highest of places And taught him teaching with seventy faces He came back with the seven books of the Torah Built the Ark, Altar, seven branch menorah Set up the Tabernacle seven times in a row For the first seven days he was Kohen Gadol But the people was to much for him to support So he set up a seventy man supreme court When his sister complained, G-d made her stay With Tzaras outside the camp for seven days An affliction like that you show to a priest He’ll quarantine you for seven days at least When he sees you again, if he still isn’t sure He might have to quarantine you seven more If he says it’s Tzaras then you wait outside Til he slaughters a bird the day you’re purified Dips a live bird, cedar wood, crimson thread And hyssop in the blood of the bird that’s dead You get sprinkled with the blood seven times by the priest Take the bird that’s alive outside to be released After that you can enter the camp, but you stay Outside of your own tent for seven more days Til the seventh day when he shaves all the hair On your head, and your beard, eyebrows, everywhere Then you bring offerings to atone for your crimes And he sprinkles you with olive oil seven times Some things we do just because G-d said We take an unblemished unworked cow that’s red Slaughter it and have the Kohen flick a spackle Of it’s blood seven times before the Tabernacle Burn it, put the ashes in some H2O That came from a river with a seven year flow When anybody touches any body passed away Purify’em with the Mayim on the third and seventh day” Then Miriam died from HASHEM’s kisses She was one of Israel’s seven prophetesses So G-d blessed her with a painless fate And she was one of seven corpses the worms never ate Just like Moshe and Aaron those three Come from a family full of prophesy But they were many others who had revelations G-d even gave seven prophets to the nations Bilaam was one of the worst on earth So Balak hired him to curse us but first They built seven altars, according to plan And offered up seven bulls, and seven rams It failed so Balak just built seven more Burnt seven bull, and seven rams like before Failed again so he did seven more like the first Still he gave us a blessing instead of curse Our enemies joined as one to attack But on seven different roads they ran right back Just like Moshe told us on the other side Of the river Jordan before he died He passed away on the seventh of Adar Never made it to the land only saw it from afar But we crossed over under Joshua’s command And celebrated Pesach in the promise land Passover extends seven days my friends And from the night after the first day ends We count seven times seven days till Shavuot Refining our souls with the seven Spheriot We go through Tiferet, Malchut, Yesod Chesed, Gevurah, Netzach, and Hod We not tzaddiks but after seven weeks We’re ready to receive the words G-d speaks When Joshua was going around Jericho and There were seven Kohanim, with seven shofars blowing They circled the city seven days in all The seventh day circled seven times round the wall We won that battle but coast wasn’t clear Cause Midian invaded for seven years Til Gideon rose up and made them run Came home a hero had seventy sons Shimshon showed those Philistine kings He could break through seven new bow strings Til Delilah pressed him, left him for dead By shaving the seven dreadlocks off his head She was bad but wise woman stands alone On seven pillars she builds up her home Ruth was a convert good as they come She was better to Naomi than seven sons Her descendant David was just another Son of Yishai with seven brothers But he was destined to sit on the throne For the first seven years he reigned in Chevron He had seven wives but that was before He met Bat-Sheva and he took one more She gave birth to Sholmo when he was alive He got married to seven hundred wives Seventy thousand men had to cut the stones Of the temple he built while he sat on the throne Took seven years, in the seventh month it was done Then he had a double seven day celebration When it was destroyed Yermiyahu was clear That the exile would last for seventy years So we sat seven decades in Bavel and waited While the date of redemption was miscalculated By Achashverosh, the king whose hand Ruled over a hundred and twenty seven lands He threw a seven day long feast for his friends His seven chamberlains, and his seven wise men One of them was Daniel who prayed for the end Of the exile end, then an angel came to him Said, “Seventy weeks,” but it wasn’t so clear Might have meant seventy more sets of seven years Since then we’ve been punished again, and again In seven different ways for our seven sins Feeling like Iyov so many mishaps He lost seven sons when their house collapsed And he had a huge flock but a fire came Seven thousand sheep just went up in flames So he sat in silence morning his plight For seven days and seven nights When the wicked stumble they meet their demise But the righteous can fall seven times and rise Five, Seven, Seven, Three is the year we’re in Waiting for the seventh millennium to begin Had the seventh Rebbe in seven seventy So how much longer will this galus be Let our enemies all be crushed at once We’ll bury their bodies for seven months Their weapons will fuel our fires for free For seven years we won’t cut down a tree Let the river spilt into seven streams Like the sea when we left from Mitzrayim I can dream, next Pesach we’ll be redeemed Have Seder all together in Yerushalayim Passover extends seven days my friends And from the night after the first day ends We count seven times seven days till Shavuot Refining our souls with the seven Spheriot We go through Tiferet, Malchut, Yesod Chesed, Gevurah, Netzach, and Hod We not tzaddiks but after seven weeks We’re ready to receive the words G-d speaks

Seven are the rules for humanity.
Seven are the questions to always ask when studying something, according to the Tiferet Yisrael commentary on Avot 2:14; this list (which begins "mi? ma?") produces a really-hard-to-get-out-of-your-head Jewish pop hit.

There are seven mitzvos in chazzal which are equivalent to all the other mitzvos as enumerated and explained in Rabbi Shlomo Volbe's seffer Hamitzvis Hashakulos
1) Whoever denies avoda zara affirms the entire Torah. Sifri Shlach on chapter 15 verse 22-23, Chulin 5a.
2) Tzitzis is equivalent to all the mitzvos. Rashi Shlach 15, 41.
3) Whoever desecrate shabbos is akin to worshipping idols which is equivalent to all the mitzvos. Rashi Shlach 15, 41. Shmos rabba 25, 12.
4) Even all the mitzvos are not equal to one word of Torah. Yerushalmi Peah 1,1.
5) Great is Mila which is equivalent to all the Mitzvos in the Torah. Nedarim 32a.
6) Tzedaka is equivalent to all the mitzvos. Bava basra 9a.

Seven spokes on the wheel of the Wheel of Time (IIRC R' Aryeh Kaplan says that the world is like a wheel in InnerSpace) that represent the seven ages of the world (with the seventh being the sabbatical era), and seven locks of indestructible heartstone seal the prison that binds the Shai'tan (i.e. Satan, yetzer hara, sitra achra).
I once read on the Internet someone theorizing that the author of the WoT series is a closet kabbalist. Could this be true?
There are seven pesukim in Tanakh that have exactly the same gematria as the brocho of netilas yodoyim. I am not entirely sure of the significance of this but there must be some. The pesukim are: Genesis 33:11, Exodus 10:8, Leviticus 20:23, Kings 2 10:36, Ezekiel 6:8, Isaiah 19:1, and Chronicles 1 15:19. They are all gematria 3339.
