Then the Lord said unto Moses, "Go in unto Pharaoh: for I have hardened his heart, and the heart of his servants, that I might show these My signs before him; 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 Jehovah." The Lord was manifesting His power, to confirm the faith of Israel in Him as the only true and living God. He would give unmistakable evidence of the difference He placed between them and the Egyptians, and would cause all nations to know that the Hebrews, whom they had despised and oppressed, were under the protection of the God of heaven.

Så sagde Herren til Moses: "Gå til Farao! Thi jeg har forhærdet hans og hans tjeneres hjerte, at jeg kan komme til at gøre disse mine tegn iblandt dem, for at du må kunne fortælle din søn og din sønnesøn, hvorledes jeg handlede med ægypterne, og om de tegn, jeg gjorde iblandt dem; så skal I kende, at jeg er Herren." Herren åbenbarede sin magt for at styrke Israels tro på ham som den eneste, sande levende Gud. Han ville give umiskendelige beviser på den forskel, han gjorde mellem dem og ægypterne, og ville lade alle folkeslag vide, at hebræerne, som de havde foragtet og undertrykt, stod under Himmelens Guds beskyttelse.
