And the angel of God appeared unto him
in a flame of fire out of the midst of a bush;
and he looked, and, behold, the bush burned with fire,
and the bush was not consumed.
God called unto him out of the midst of the bush, :
‘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.
Then God said: ‘I have surely seen the affliction

of My people that are in Egypt,
and have heard their cry ‘

; for I know their pains;

{Exodus 3:2-7}
