Exodus 10:2

WEB

and that you may tell in the hearing of your son, and of your son's son, what things I have done to Egypt, and my signs which I have done among them; that you may know that I am the Lord."

KJV

And that thou mayest tell in the ears of thy son, and of thy son’s son, what things I have wrought in Egypt, and my signs which I have done among them; that ye may know how that I am the LORD.

Commentary

And that thou mayest tell in the ears of thy son, and of thy son's son,.... Not of his sons and grandsons only; for Moses he re, as Aben Ezra observes, was in the stead of Israel; and the sense is, that it should be told to their posterity in all succeeding ages: what things I have wrought in Egypt; the plagues that he inflicted on the Egyptians: and my signs which I have done amongst them; meaning the same things which were signs: that ye may know how that I am the Lord; that their God is the true Jehovah, and the one only living and true God; the Lord God omnipotent, omniscient, omnipresent, infinite, and eternal.
