'Teach' in the Bible

many peoples will come and say, "Come, let us go up to the Lord's mountain, to the temple of the God of Jacob, so he can teach us his requirements, and we can follow his standards." For Zion will be the center for moral instruction; the Lord will issue edicts from Jerusalem.

The leaders and the highly respected people are the head, the prophets who teach lies are the tail.

Who is the Lord trying to teach? To whom is he explaining a message? Those just weaned from milk! Those just taken from their mother's breast!
