(1.) He shall be guarantee of the treaty of peace between God and man: I will give thee for a covenant of the people. This we had before (ch. xlii. 6), and it is here repeated as faithful, and well worthy of all acceptation and observation. He is given for a covenant, that is, for a pledge of all the blessings of the covenant. It was in him that God was reconciling the world to himself; and he that spared not his own Son will deny us nothing. He is given for a covenant, not only as he is the Mediator of the covenant, the blessed days-man who has laid his hand upon us both, but as he is all in all in the covenant. All the duty of the covenant is summed up in our being his; and all the privilege and happiness of the covenant are summed up in his being ours.
