Thematic Bible: Moses' law protected the mother from being taken with the young

When a bird's nest shall be found before thee in the way in any tree or upon the earth, the young broods or the eggs, and the mother reclining upon the young birds, or upon the eggs, thou shalt not take the mother upon the sons. Sending, thou shalt send away the mother, and the sons thou shalt take to thee, so that it shall be well to thee and thou prolongedst the days.
