to give Aaron and his sons and all the people of Israel the following regulations. When any Israelite or any foreigner living in Israel presents a burnt offering, whether as fulfillment of a vow or as a freewill offering, the animal must not have any defects.
To be accepted, it must be a male without any defects.
If you offer any animal that has any defects, the Lord will not accept it. 1
