Leviticus 22:27-29

New Living Translation

²⁷ “When a calf or lamb or goat is born, it must be left with its mother for seven days. From the eighth day on, it will be acceptable as a special gift to the Lord. ²⁸ But you must not slaughter a mother animal and her offspring on the same day, whether from the herd or the flock. ²⁹ When you bring a thanksgiving offering to the Lord, sacrifice it properly so you will be accepted.
