What is the excerpt below about?

Moreover He said: 'I am the God of thy father, the God of
Abraham, the God of Isaac, and the God of Jacob.' And Moses
hid his face; for he was afraid to look upon God. And the LORD
said: 'I have surely seen the affliction of My people that are in
Egypt, and have heard their cry by reason of their taskmasters;
for I know their pains; and I am come down to deliver them out
of the hand of the Egyptians, and to bring them up out of that
land unto a good land and a large, unto a land flowing with milk
and honey. "
