Exodus 3:9

Now therefore, behold, the cry of the children of Israel is
come unto me
See ( Exodus 2:23 ) : and I have also seen the oppression wherewith the Egyptians oppress
them;
which is repeated to observe the great notice he took of it; and the reason of his descent and appearance in this wonderful manner, as well as of the urgent necessity of Moses's going to deliver the people from their oppression.
