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 Hebrews 6:18 ) .
