I [am] the Lord your God
Their Creator, Preserver, and Benefactor, their Lord and Sovereign, their covenant God and Father:
which brought you out of the land of Egypt, to be your God;
to make it appear that he was their God in a special relation, and that he took the special care and government of them; and which was manifest by the system of laws he gave them to observe, as well as by his provision for them on all accounts, and by his protection of them:
I [am] the Lord your God;
who had a right to enact laws, and enjoin the observance of them, as he was the Lord Jehovah; and they were under obligation to regard them, as he was not only their Creator but their covenant God and Father, who had bestowed his favours liberally on them.
