Exodus 7:5 Meaning and Commentary

Exodus 7:5

And the Egyptians shall know that I am the Lord
Jehovah, the one only true and living God; this they should know by the judgments executed upon them, and be obliged to acknowledge it:

when I stretch forth mine hand upon Egypt:
especially the last time, to destroy the firstborn:

and bring out the children of Israel from among them;
by which it would appear that he was mightier than they, and obtained the end for which the plagues were inflicted on them.
