IV. Here is an account of the great benefit procured for mankind by the Messiah, which is redemption from extreme misery, typified by the deliverance of the Jews out of their captivity in Babylon (v. 11): "As for thee also (thee, O daughter of Jerusalem! or thee, O Messiah the Prince!) by the blood of thy covenant, by force and virtue of the covenant made with Abraham, sealed with the blood of circumcision, and the covenant made with Israel at Mount Sinai, sealed with the blood of sacrifices, in pursuance and performance of that covenant, I have now of late sent forth thy prisoners, thy captives out of Babylon, which was to them a most uncomfortable place, as a pit in which was no water." It was part of the covenant that, if in the land of their captivity, they sought the Lord, he would be found of them, Lev. xxvi. 42, 44, 45; Deut. xxx. 4. It was by the blood of that covenant, typifying the blood of Christ, in whom all God's covenants with man are yea and amen, that they were released out of captivity; and this was but a shadow of the great salvation wrought out by thy King, O daughter of Zion! Note, A sinful state is a state of bondage; it is a spiritual prison; it is a pit, or a dungeon, in which there is no water, no comfort at all to be had. We are all by nature prisoners in this pit; the scripture has concluded us all under sin, and bound us over to the justice of God. God is pleased to deal upon new terms with these prisoners, to enter into another covenant with them; the blood of Christ is the blood of that covenant, purchased it for us and all the benefits of it; by that blood of the covenant effectual provision is made for the sending forth of these prisoners upon easy and honourable terms, and proclamation made of liberty to the captives and the opening of the prison to those that were bound, like Cyrus's proclamation to the Jews in Babylon, which all those whose spirits God stirs up will come and take the benefit of.
