Deuteronomy 22:6-7

ASV(i) 6 If a bird's nest chance to be before thee in the way, in any tree or on the ground, with young ones or eggs, and the dam sitting upon the young, or upon the eggs, thou shalt not take the dam with the young: 7 thou shalt surely let the dam go, but the young thou mayest take unto thyself; that it may be well with thee, and that thou mayest prolong thy days.
