In Mishnah Torah, Hilchot Melachim 12:5, Rambam quotes Isaiah 11:9 using the phrase:

כִּי מָלְאָה הָאָרֶץ דֵּעָה אֶת ה' כַּמַּיִם לַיָּם מְכַסִּים

This is commonly translated as, That the earth will be filled with knowledge of G-d like the waters of the ocean cover.

This means that the word de'ah (דעה) is understood as an adjective modifying a noun in the sentence. The English phrase knowledge of G-d would be da'at HaShem (דעת הוי). What is implied by changing the Hebrew phrase to de'ah et-HaShem?

In context of the full phrase de'ah et HaShem, the objective particle (called in English grammar a Connective Conjunction) et is associated to G-d, meaning that the word de'ah is a verb of some kind implying an action or process. It looks like it is from the verb root yada (ידע) meaning to know. But the conjugation of that verb root doesn't drop the letter Yud to this form.

And in the context of the full sentence from Isaiah which is:

לֹֽא־יָרֵ֥עוּ וְלֹֽא־יַשְׁחִ֖יתוּ בְּכָל־הַ֣ר קָדְשִׁ֑י כִּֽי־מָלְאָ֣ה הָאָ֗רֶץ דֵּעָה֙ אֶת־יְהוָ֔ה כַּמַּ֖יִם לַיָּ֥ם מְכַסִּֽים׃

It emphasizes even more that future negative actions will not take place as a consequence of the earth being filled with some kind of future process.

What is that process and what is the verb root, proper binyan and conjugation? Meaning, is this something done by one individual, or a group of individuals?

    Why would a Yud be there? It shows up many times in Tanach without a Yud. את מי יורה דעה or ויש דעה בעליון or ורעו אתכם דעה והשכיל. And that's a normal form for a root beginning in Yud. Like ליעץ and עצה advice. Or וישן and שנה sleep. Or ליחמנה and חמה heat/excitement. Or ילד and לדה birth. Lots of examples of this very normal phenomenon. – Double AA Jun 5 at 17:55
  • All of your examples are not verbs. They are where דעה is being used as a noun. But as mentioned in my question, because of the preposition את, which indicates the direct object (G-d's name) is the receiver of the action, it indicates that דעה is a verb. Just to point out, the letter 'Heh' in the word דעה appears to be a pronominal suffix relating to the 'name' of G-d. The preposition את emphasizes that relationship. – Yaacov Deane Jun 13 at 15:05

It seems from the classical meforshim that the word דעה - dei'oh is to be understood as a verb in its infinitive form לדעת - lo'da'as, to know. The infinitive form can refer to both the individual or a group of individuals. I have quoted Targum Yonoson and Rashi (whose source in this case is the Targum).

תרגום יונתן: ארי תתמלי ארעא למידע ית דחלתא דה' כמיא דלימא חפן

רש"י: דעה את ה' - לדעת את ה' עכ"ל

Based on the context of the perek, chapter, the Malbim suggests that this verse continues to refer to the animal kingdom. There will be a שינוי טבע - shinui teva, a change in nature, that even animals who are not equipped with human intelligence will in some way be overcome with the knowledge of G-d.

מלבי"ם: כי מלאה. יאמר במליצתו שהכרת ה' תתפשט כל כך עד שגם החיות הטורפות יכירו כי הגיע עת התיקון, הגם שאין כח השכל אצלם, ומדמה זה למים המכסים חפירת הים שאין מקום מעצור בפני המים שלא יכסו אותו, כן גם חומר הבע"ח הבלתי מוכן להשכלה לא יעצור בפני ידיעת ה' אשר תתפשט על כל בשר, והיא מליצה על שינוי טבע הבע"ח בדבר ה' עכ"ל

  • It’s a good beginning however, Rambam uses the Hebrew original from Isaiah and it is not the infinitive of the verb root. And looking at specific grammar (root, gezerah & Binyan) usage here (in Mishnah Torah) is important to proper comprehension of the halacha. Why is Rambam pulling this partial quote here (the end & completion of his whole sefer?) Why is that relevant? – Yaacov Deane Jun 12 at 23:35

    The question is not on the Rambam. The Rambam is merely quoting the verse as a proof text for that which he writes that the whole world will be involved in understanding G-d. We, the readers, are assumed to be familiar with the verse. The question is on the verse. If indeed the intent is the infinitive form, as the meforshim wrote, why wouldn't it just be written that way. – BigJohn Jun 12 at 23:43
  • On the contrary, from the very beginning when I posted this I emphasized that it was specifically in the context of this halacha found in Mishnah Torah. People tried to eliminate that detail insisting that it was only about the Prophet or grammar in general. They have since deleted their comments so you only see what is posted presently. But both the question heading and body of the question specifically connect this to the halacha cited. The question tags do too, unless someone removed them again. – Yaacov Deane Jun 12 at 23:50

    I agree with those people. The burden of proof is on you to prove that the Rambam is doing more than merely quoting a source text. I think that you should edit the question and explain based on other examples that the Rambam isn't just quoting here, but rather giving us a new interpretation of the verse. – BigJohn Jun 13 at 0:02
  • All in due time. But I would strongly encourage you to continue to develop your answer. There are good ideas there. – Yaacov Deane Jun 13 at 1:18

As pointed out in the question, because of the use of the connecting conjunction (את) in the phrase, "דֵּעָה֙ אֶת־יְהוָ֔ה", it is clear that דעה is a verb. And as Rashi and others point out to the source of Rambam's quote in Isaiah, it is from the concept of דעת. The verb root would then be י-ד-ע.

This is classified as Gizrat Peh-Yud, Lamed-Gronit (with the letter Ayin), which makes this a somewhat rare, double-weak verb structure with a Peh-Yud.

The letter Heh at the end of the verb is only supportive of the object in the phrase and indicates that the object is feminine.

In the context of the complete sentence from Isaiah and also the usage by Rambam in the Mishnah Torah which is discussing the final redemption, the phrase should be future tense, which in terms of the form of the conjugation and nekudot suggests that the Binyan is Pi'el, 3rd person, singular, masculine. Because of the unusual double-weak root, the opening letter Yud appears to drop leaving only Dalet-Ayin (דע). It's worth noting that this particular verb form only appears once throughout all of Tanach in the Isaiah quoted.

Considering the complete phrase brought by Rambam, the letter Heh appears to be indicating (meaning somech to) the name of G-d (שם, which can be either masculine or feminine in Hebrew depending upon the context).

It's worth noting that this also relates to the concept of Shem being feminine as used in the first word of the Shema prayer. (שמ-ע, the intention is to draw the 7 middot of Imma (intellect), represented by the large letter Ayin, into Nukvah (physical material expression within creation), the feminine as daughter, which is the concept of Shem, name.)

When considering the actual meaning of the verb root, Machberet Menachem in connection with the two letter root ד-ע, indicates that the root has several meanings, including the idea of uncovering or revealing (גלוי), and also actual union like in sexual intercourse, where husband (G-d is referred to as איש מלחמה in the Song of the Sea) and wife become one flesh.

In addition to these ideas, Sefer HaShorashim of Rabbi Yonah Ibn Yanach quotes Sefer Otot HaRifayon and associates it to Iyov 9:5 and the concept of feeling or sensing tangibly.

And the Sefer HaShorashim of the Radak also brings these ideas and adds in relation to the posuk from Isaiah that it also has a connotation of how He is the source of this action, particularly because of the usage of את in the phrase.

And this leads to trying to understand the concept of name as used here, like the name of G-d.

The concept of name as used in the Torah is not the actual essence of that which it refers to, meaning in this case the essence of G-d. It is only a vessel, a tool so to speak, intended for others to connect and relate to the one associated with that name.

This idea is discussed in chassidut and many other places in regard to the first of the ten commandments which begins with Anochi (אנכי), which is not a name but a reference to G-d at His essence, which transcends the concept of names altogether. This is sometimes called Ain Sof (אין סוף) in kabbalistic literature. And G-d at His essence identifies Himself to us via the name used in that first commandment.

In this context, the He, meaning the masculine operator of the phrase (remember the binyan of the verb is 3rd person, masculine, singular), refers to G-d at His essence.

Through G-d manifesting the union with His name, meaning the feminine part of this phrase indicated by the ending letter Heh in דעה, which is associated to G-d's four letter name, there is a revelation or uncovering of G-d's essence, meaning what transcends all of creation, in the world, which will be physically and materially sensed and perceived over all of His creation, like the waters of the sea cover over. This is the meaning of the words which Rambam brings in Hilchot Melachim 12:5.

This is often expressed by the saying of our Sages: For the sake of the unification of the Holy One, blessed be He and His Shechina (Divine Presence). It is also the meaning behind saying: Blessed be He and blessed be His name.

It might seem like an outlandish idea to think that Rambam in his Mishnah Torah, a book of psak halacha, would be communicating such a deep, mystical and profound idea that doesn't seem to be the plain meaning at all. Until you consider what Rambam writes in his introduction to the Mishnah Torah, an introduction which was actually written after he had completed the entire work.

In section 1 of the introduction, Rambam explains that the entire Torah was given to Moshe Rabbeinu at Har Sinai both the written portion found in Tanach and the entire oral Torah, meaning all explanations including the entire Talmud, every Midrash and all the Kabbalistic and Chassidic teachings (Ma'aseh Merkava and Ma'aseh Bereshit). Nothing was excluded.

And then Rambam goes on to explain in section 41 of his introduction that he has intentionally written this entire oral Torah within his Mishnah Torah, in a very precise, refined and abbreviated language to such an extent that if read and understood correctly, no other book about the oral Torah would be necessary to anyone.

And Rambam goes even further in regard to this idea in section 42 to his introduction to say that his intent in writing the Mishnah Torah was that a person should first read the section of the written Torah and afterward read the corresponding section in the Mishnah Torah and from this would know the entire oral Torah and not need any other book.

This also means that Rambam intended the Mishnah Torah to be read in connection with the daily and weekly portion of the Tanach and that it was composed in parallel to the weekly reading.

And just like the beginning of the written Torah, parshat Bereshit, begins with the details of the beginning of Creation for example, including the concept of Adam knew Chava (אדם ידע חוה), the Mishnah Torah also deals with that same subject in Hilchot Yesodei HaTorah chapters 1 through 4 (for example see 2:9-10 and 4:9-13 which also deal with this subject of Da'at).

And looking at the conclusion of the written Torah, which describes preparing to enter the land of Israel and establishing G-d's Kingdom through the King of the Jewish people. (Note also Devarim 34:10-12 which, like with the beginning, again mentions the subject of Da'at (See Rashi there) and also the Yad HaChazakah, another name for the Mishnah Torah which contains 14 books (י״ד). These are the subject of the conclusion of Rambam's Mishnah Torah also.

That like the saying of our Sages, The end is wedged in the beginning and the beginning is wedged in the end. And this is also alluded to in the last letter of the written Torah (ל) together with its first letter (ב) of the Torah (which is started immediately upon the conclusion of the final parsha) which totals 32, a reference to the 32 times G-d is mentioned in the Creation (like is discussed in the introduction to Sefer Yetzirah).
