Certainly the doctrine of redemption by the LORD JESUS is all along veiled, under this doctrine of vows and dedications: so that in every gift an eye is supposed to be had to this. All things are the LORD'S by right, and the redemption implies our forfeiture of all pretensions. Ecclesiastes 5:1.

Leviticus 27:9-13
9 And if it be a beast, whereof men bring an offering unto the LORD, all that any man giveth of such unto the LORD shall be holy.
10 He shall not alter it, nor change it, a good for a bad, or a bad for a good: and if he shall at all change beast for beast, then it and the exchange thereof shall be holy.
11 And if it be any unclean beast, of which they do not offer a sacrifice unto the LORD, then he shall present the beast before the priest:
12 And the priest shall value it, whether it be good or bad: as thou valuest it, who art the priest, so shall it be.
13 But if he will at all redeem it, then he shall add a fifth part thereof unto thy estimation.
