Leviticus 22:19-21

¹⁹it must be an animal that has no defects, in order that it will be accepted by me.

²⁰Do not bring any animals that have defects, because I will not accept them as an offering from you.

²¹Similarly, when someone brings from his cattle or sheep or goats an offering to maintain fellowship with me, either to fulfill a promise that he made to me or to be a voluntary offering, in order that I will accept it, it must have no defects DOU or blemishes.
