Справочник к Дварим 27:6

Thus the Torah commands that “if you find on your way a nest of birds on a tree or on the ground containing birds or eggs you shall not take the mother with her offspring but you shall send the mother away and the offspring you may take for yourself in order that you may live long years. (Deut. 27:6, 7.) The same reward is also held out for the fulfillment of the commandment of honoring one’s father and mother: “Your years will be long and your portion will be good.” (Deut. 8:16.)
