Conditions to be Satisfied by the Victims in the case of certain sacrifices. This set of rules is given to Aaron and his sons as containing guidance for the priests-' examination of the animals. For vows and freewill offerings (Leviticus 1-3) the victim is to be a male, without blemish. In the case of a peace offering, which is to accomplish a vow or freewill offering (un-mentioned in Leviticus 3), the sex of the animal is not mentioned, but certain blemishes are specified. Malformations are allowed in the case of freewill offerings, but not of vows, which are of the nature of a debt. Castration renders an animal unfit for sacrifice, even if the operation had been performed before it came into Hebrew hands; it is a destruction (RV corruption) of its true nature.
Leviticus 22:17-25
17 And the LORD spake unto Moses, saying,
18 Speak unto Aaron, and to his sons, and unto all the children of Israel, and say unto them, Whatsoever he be of the house of Israel, or of the strangers in Israel, that will offer his oblation for all his vows, and for all his freewill offerings, which they will offer unto the LORD for a burnt offering;
19 Ye shall offer at your own will a male without blemish, of the beeves, of the sheep, or of the goats.
20 But whatsoever hath a blemish, that shall ye not offer: for it shall not be acceptable for you.
21 And whosoever offereth a sacrifice of peace offerings unto the LORD to accomplish his vow, or a freewill offering in beeves or sheep,c it shall be perfect to be accepted; there shall be no blemish therein.
22 Blind, or broken, or maimed, or having a wen, or scurvy, or scabbed, ye shall not offer these unto the LORD, nor make an offering by fire of them upon the altar unto the LORD.
23 Either a bullock or a lambd that hath any thing superfluous or lacking in his parts, that mayest thou offer for a freewill offering; but for a vow it shall not be accepted.
24 Ye shall not offer unto the LORD that which is bruised, or crushed, or broken, or cut; neither shall ye make any offering thereof in your land.
25 Neither from a stranger's hand shall ye offer the bread of your God of any of these; because their corruption is in them, and blemishes be in them: they shall not be accepted for you.
