I. God here takes to himself such titles of his honour as were very encouraging to them. He is the Lord their Redeemer, not only he will redeem them, but will take it upon him as his office and make it his business to do so. If he be their God, he will be all that to them which they need, and therefore, when they are in bondage, he will be their Redeemer. He is the Holy One of Israel (v. 14), and again (v. 15), their Holy One, and therefore will make good every word he has spoken to them. He is the Creator of Israel, that made them a people out of nothing (for that is creation), nay, worse than nothing; and he is their King, that owns them as his people and presides among them.
