He sent redemption unto his people,.... Or one to redeem them, who effected it; Moses to redeem Israel out of Egypt, and Christ to redeem his people from sin, Satan, and the law, and who has done it; and having obtained eternal redemption, he sent his ministers to publish it in the world, and his Spirit to apply it, and to show his people their interest in it; and make it over to them, and the blessings of it, that they may enjoy it, and all the comforts and advantages arising from it; temporal redemption, as typical of the spiritual and eternal one, is here meant.
He hath commanded his covenant for ever; which cannot be the covenant of circumcision, or that at Sinai, neither of which were for ever; but the covenant of grace made with Christ, and which stands fast with him for ever; it is everlasting, sure, and can never be removed; its blessings and promises are for ever; and it is so made and framed, and so kept and observed, as that it shall always continue, which is meant by its being "commanded": as well as it may denote the decree and resolution of God never to break and alter it; see Ps 89:3.
