KJV
And say unto them, Thus saith the Lord
GOD; In the day when I chose Israel, and lifted up mine hand unto the seed of
the house of Jacob, and made myself known unto them in the land of Egypt,
when I lifted up mine hand unto them, saying, I [am] the LORD your God;
BSB
and tell them that this is what the Lord GOD says: On the day I chose Israel, I swore an oath to the descendants of the house of Jacob and made Myself known to them in the land of Egypt. With an uplifted hand I said to them, ‘I am the LORD your God.’
