'Without 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,

but with the precious blood of the Messiah, like that of a lamb without blemish or defect.
