Leviticus 27:27 Meaning and Commentary

Leviticus 27:27

And if [it be] of an unclean beast
This is to be understood, not of the firstling of unclean creatures in common, which were to be redeemed with a lamb, and not with money, according to the estimation of the priest, and a fifth part added to that; but of such as were sanctified, or vowed, for the reparation of the sanctuary, as Jarchi notes:

then he shall redeem [it] according to thine estimation;
the price the priest should set upon it, how much it was worth in his judgment:

and shall add a fifth [part] of it thereto;
to the price, set upon a fifth part of that over and above the sum; this the sanctifier, or he that made the vow, was obliged to pay, if he thought fit to redeem it:

or if it be not redeemed;
by him, he does not choose to give the price, and the fifth part:

then it shall be sold according to thy estimation;
to another man, without the fifth part, that chooses to purchase it, and then the purchase money was laid out for sacred uses.

Leviticus 27:27 In-Context

25 All prices shall be set according to the official standard.
26 The first-born of an animal already belongs to the Lord, so no one may dedicate it to him as a freewill offering. A calf, a lamb, or a kid belongs to the Lord,
27 but the first-born of an unclean animal may be bought back at the standard price plus an additional 20 percent. If it is not bought back, it may be sold to someone else at the standard price.
28 None of you may sell or buy back what you have unconditionally dedicated to the Lord, whether it is a human being, an animal, or land. It belongs permanently to the Lord.
29 Not even human beings who have been unconditionally dedicated may be bought back; they must be put to death.
