This is getting into a very symbolic area so I'm not going to claim this answer as being fully respected as an Orthodox interpretation. It actually bleeds into Torah archeology/anthropology and relates to understandings of symbolism historically. The idea is actually promoted in a lecture by a Dr. Elaine Goodfriend.
There's an idea that the Torah was broken into five books as each of the five books represent a "finger" of Hashem. The idea is that when Hashem gave the Torah to Moses, he was essentially putting out his hand for the Jewish people to take.
Hands are pretty major symbols in Judaism as they relate to a lot of rituals and practices.
Washing of one's hands for ritual purity.
Hands being raised for the priestly blessing.
Blessing of the children by placing one's hands on their heads.
Our hands are emphasized in many ways and this ties into the hand of Hashem on some level.
We see the language of "hands" being used in the language of our writings as it references Hashem's "hand" during times when he acted on behalf of the Jewish people or intervened in the world. While these are not literal hands, the hand indicates an interaction and involvement on either a physical or spiritual level.
the word of the LORD came to the priest Ezekiel son of Buzi, by the
Chebar Canal, in the land of the Chaldeans. And the hand of the LORD
came upon him there. - Ezekiel 1:3
For I was ashamed to ask of the king a band of soldiers and horsemen to help us against the enemy on the road: because we had spoken to the king, saying, The hand of our God is upon all those who seek him for good; but his power and his wrath are against all those who forsake him.” - Ezra 8:22
then the hand of the LORD will strike your livestock in the fields—the horses, the asses, the camels, the cattle, and the sheep—with a very severe pestilence. -Exodus 9:3
The idea is that the Torah is an interaction. Hashem gave us commandments and the ability for us to live and walk and serve at his side. That was his hand reaching out to us so that we could be pulled up.
Again, this is not necessarily an Orthodox interpretation but I appreciate the symbolism and the rationality used in it. Thought you might also appreciate it.
