Leviticus 22:18-19

“Give Aaron and his sons and all the Israelites these instructions, which apply both to native Israelites and to the foreigners living among you. “If you present a gift as a burnt offering to the LORD, whether it is to fulfill a vow or is a voluntary offering, you will be accepted only if your offering is a male animal with no defects. It may be a bull, a ram, or a male goat.
