Ezekiel 20:5

And say unto them, thus saith the Lord God,.... Here begins the account of their fathers; of God's unmerited goodness to them, and of their sins and transgressions against him, and how it fared with them:

in the day when I chose Israel; to be his peculiar people, above all people on the face of the earth; when he declared his choice of them, and made it appear that he had chosen them, and distinguished them, by special blessings and favours bestowed on them:

and lifted up mine hand to the seed of the house of Jacob; the posterity of Jacob or Israel, to whom the Lord swore that he would do such and such things for them; of which the lifting up the hand was a token; it is a gesture used in swearing, Daniel 12:7; and so the Targum,

"and I swore unto them by my word:''

and made myself known unto them in the land of Egypt: by his name Jehovah; by the prophets he sent unto them, Moses, Aaron, and Miriam; and by the miracles he wrought among them:

when I lifted up mine hand unto them, saying, I [am] the Lord your God: making promise of it, declaring it unto them, confirming it with an oath; see Hebrews 6:17.
