Deuteronomy 15:19-21

Amplified Bible, Classic Edition

¹⁹ All the firstling males that are born of your herd and flock you shall set apart for the Lord your God; you shall do no work with the firstling of your herd, nor shear the firstling of your flock.

²⁰ You shall eat it before the Lord your God annually in the place [for worship] which the Lord shall choose, you and your household.

²¹ But if it has any blemish, if it is lame, blind, or has any bad blemish whatsoever, you shall not sacrifice it to the Lord your God.
