“When a bull, a sheep or a goat is born, then it is to remain seven days with its mother, and from the eighth day onward it will be accepted as the gift of an offering made by fire to Adonai.
Moreover, you are not to offer the food of your God from the hand of an outsider from any of these animals. For their corruption is within them—they have a defect. They will not be accepted on your behalf.”
So it will rest on Aaron’s forehead, so that Aaron will bear away the iniquity committed regarding the holy things, which Bnei-Yisrael set apart as all their holy gifts. It is to be always on his forehead, so that they may have favor before Adonai.
