Leviticus 27:32-34

Good News Translation

³² One of every ten domestic animals belongs to the Lord. When the animals are counted, every tenth one belongs to the Lord. ³³ You may not arrange the animals so that the poor animals are chosen, and you may not make any substitutions. If you do substitute one animal for another, then both animals will belong to the Lord and may not be bought back.

³⁴ These are the commands that the Lord gave Moses on Mount Sinai for the people of Israel.
