Leviticus 22:17-33 - Acceptable Offerings
17 And the LORD spake unto Moses, saying, 18 "Speak unto Aaron and his sons and unto all the children of Israel, and say unto them, 'Whatsoever he be of the house of Israel or stranger in Israel that will offer his offering: whatsoever vow or freewill offering it be which they will offer unto the LORD for a burnt offering to reconcile them selves, 19 it must be a male without blemish of the oxen, sheep or goats. 20 Let them offer nothing that is deformed for they shall get no favour therewith.
21 If a man will offer a peace offering unto the LORD and separate a vow or a freewill offering of the oxen or the flock, it must be without deformity, that it may be accepted. There may be no blemish therein: 22 whether it be blind, broken, wounded or have a wen, or be mangy or scabbed; see that ye offer no such unto the LORD, nor put an offering of any such upon the altar unto the LORD. 23 An ox or a sheep that hath any member out of proportion, mayst thou offer for a freewill offering: but in a vow it shall not be accepted. 24 Thou shalt not offer unto the LORD that which hath his stones bruised, broken, plucked out or cut away, neither shalt make any such in your land, 25 neither of a stranger's hand shall ye offer an offering to your God of any such. For they mar all in that they have deformities in them, and therefore cannot be accepted for you.'"
26 And the LORD spake unto Moses, saying, 27 "When an ox, a sheep or a goat is brought forth, it shall be seven days under the dam. And from the eighth day forth, it shall be accepted unto a gift in the sacrifice of the LORD. 28 And whether it be ox or sheep, ye shall not kill it and her young both in one day. 29 When ye will offer a thank offering unto the LORD, ye shall so offer it that ye may be accepted. 30 And the same day it must be eaten up, so that ye leave none of it until the morrow. For I am the LORD.
31 Keep now my commandments and do them, for I am the LORD. 32 And pollute not my holy name, that I may be hallowed among the children of Israel. For I am the LORD which hallow you, 33 and brought you out of the land of Egypt, to be your God: for I am the LORD."
