'Blemish' in the Bible
Your lamb is to be a year old male without blemish. You may take it from the sheep or from the goats.
"This is what you are to do to them in order to consecrate them to serve me as priests: Take a young bull, two rams without blemish,
He is to bring an offering to the LORD, a year old male lamb, and a year old ewe female lamb, both without blemish, for a sin offering and a ram without blemish for a peace offering,
If it has a blemish lameness, blindness, or any kind of defect you must not sacrifice it to the LORD your God.
If I have stepped away from the way, or if my heart covets whatever my eyes see, or if some other blemish clings to my hands,
My darling, you are altogether beautiful and there is no blemish in you.
but with the precious blood of the Messiah, like that of a lamb without blemish or defect.
