Leviticus 22:19-25 you shall offer of your own free will a male without blemish from the cattle, from the sheep, or from the goats. Whatever has a defect, you shall not offer, for it shall not be acceptable on your behalf. And whoever offers a sacrifice of a peace offering to the LORD, to fulfill his vow, or a freewill offering from the cattle or the sheep, it must be perfect to be accepted; there shall be no defect in it. Those that are blind or broken or maimed, or have an ulcer or eczema or scabs, you shall not offer to the LORD, nor make an offering by fire of them on the altar to the LORD. Either a bull or a lamb that has any limb too long or too short you may offer as a freewill offering, but for a vow it shall not be accepted. ‘You shall not offer to the LORD what is bruised or crushed, or torn or cut; nor shall you make any offering of them in your land. Nor from a foreigner’s hand shall you offer any of these as the bread of your God, because their corruption is in them, and defects are in them. They shall not be accepted on your behalf.’”

There you shall bring all that I command you: your burnt offerings, your sacrifices, your tithes, the heave offerings of your hand, and all your choice offerings which you vow to the LORD.
Deuteronomy 12:13 Take heed to yourself that you do not offer your burnt offerings in every place that you see;
Malachi 1:6-8 " A son honors his father, And a servant his master. If then I am the Father, Where is My honor? And if I am a Master, Where is My reverence? Says the LORD of hosts To you priests who despise My name. Yet you say, "In what way have we despised Your name?" " You offer defiled food on My altar, But say, " In what way have we defiled You?" By saying, " The table of the LORD is contemptible." And when you offer the blind as a sacrifice, Is it not evil? And when you offer the lame and sick, Is it not evil? Offer it then to your governor! Would he be pleased with you? Would he accept you favorably?' Says the LORD of hosts.
Exodus 12:48-49 And when a stranger dwells with you and wants to keep the Passover to the LORD, let all his males be circumcised, and then let him come near and keep it; and he shall be as a native of the land.
