Devarim 22:6-8

Orthodox Jewish Bible

⁶ If a bird’s ken (nest) chance to be before thee in the way in any tree, or on the ground, whether they be young ones, or eggs, and the mother is roosting upon the young, or upon the eggs, thou shalt not take the mother with the young;

⁷ But thou shalt in any wise let the mother go, and take the young to thee; that it may be well with thee, and that thou mayest prolong thy yamim.

⁸ When thou buildest a bais chadash, then thou shalt make a parapet for thy roof, that thou bring not dahm (blood guiltiness) upon thine bais, if any fall from thence.
