The covenant here spoken of means the renewal of that gracious one the Lord had vouchsafed in times past, when he formed Israel into a church; in which God graciously said, I will be their God, and they shall be my people. Implying the people's hearty and joyful consent to have God for their God in a covenant way, as the God of Abraham, Isaac, and Jacob. Exodus 19:5-6.
