Deuteronomy 22:6-7

New Revised Standard Version

⁶ If you come on a bird’s nest, in any tree or on the ground, with fledglings or eggs, with the mother sitting on the fledglings or on the eggs, you shall not take the mother with the young. ⁷ Let the mother go, taking only the young for yourself, in order that it may go well with you and you may live long.
