Knew them… That is, he had respect to them, he cast a merciful eye upon them.

Exodus Chapter 3

God appeareth to Moses in a bush, and sendeth him to deliver Israel.

3:1. Now Moses fed the sheep of Jethro, his father in law, the priest of Madian: and he drove the flock to the inner parts of the desert, and came to the mountain of God, Horeb.

3:2. And the Lord appeared to him in a flame of fire out of the midst of a bush: and he saw that the bush was on fire, and was not burnt.

The Lord appeared… That is, an angel representing God, and speaking in his name.

3:3. And Moses said: I will go, and see this great sight, why the bush is not burnt.

3:4. And when the Lord saw that he went forward to see, he called to him out of the midst of the bush and said: Moses, Moses. And he answered: Here I am.

3:5. And he said: Come not nigh hither, put off the shoes from thy feet; for the place, whereon thou standest, is holy ground.

3:6. And he said: I am the God of thy father, the God of Abraham, the God of Isaac, and the God of Jacob. Moses hid his face: for he durst not look at God.
