Exodus 7:17 Meaning and Commentary

Exodus 7:17

Thus saith the Lord, in this thou shalt know that I am the
Lord
By the following instance of his power and vengeance:

behold, I will smite with the rod that is in my hand;
which though in the hand of Moses, ( Exodus 7:18 ) yet he being his ambassador, and representing him, is said to be in the hand of the Lord; and with this he threatens to smite

upon the waters which are in the river;
the river Nile, and the canals thereof:

and they shall be turned to blood;
and if this river was their god, it would abundantly appear that the God of the Hebrews was Jehovah, and above all gods, and particularly above theirs.
