Jonah 2:9

But I will sacrifice unto thee - I will make a sincere vow, which, as soon as my circumstances will permit, I will faithfully execute; and therefore he adds, "I will pay that which I have vowed."

Salvation is of the Lord - All deliverance from danger, preservation of life, recovery from sickness, and redemption of the soul from the power, guilt, and pollution of sin, is from Jehovah. He alone is the Savior, he alone is the Deliverer; for all salvation is from the Lord.

But (And) with the voice of thanksgiving will I((would I fain) sacrifice unto Thee; what I have vowed, I would pay - He does not say, I will, for it did not depend upon him. Without a further miracle of God, he could do nothing. But he says, that he would nevermore forsake God. The law appointed sacrifices of thanksgiving; Leviticus 7:12-15. these he would offer, not in act only, but with words of praise. He would "pay what he had vowed," and chiefly himself, his life which God had given back to him, the obedience of his remaining life, in all things. For (Ecclesiasticus 35:1) "he that keepeth the law bringeth offerings enough; he that taketh heed to the commandments offereth a peace-offering." Jonah neglects neither the outward nor the inward part, neither the body nor the soul of the commandment.

Salvation is of (literally to) the Lord - It is wholly His; all belongs to Him, so that none can share in bestowing it; none can have any hope, save from Him. He uses an intensive form, as though he would say, strong "mighty salvation" . God seems often to wait for the full resignation of the soul, all its powers and will to Him. Then He can show mercy healthfully, when the soul is wholly surrendered to Him. So, on this full confession, Jonah is restored, The prophet's prayer ends almost in promising the same as the mariners. They "made vows;" Jonah says, "I will pay that I have vowed." Devoted service in the creature is one and the same, although diverse in degree; and so, that Israel might not despise the pagan, he tacitly likens the act of the new pagan converts and that of the prophet.

2:9 Vowed - Which probably was to go to Nineveh, and preach what God commanded him. The Lord - He only can save.
