law, right, custom, here prescribed for them: under Aaron their father; that is, him who was high priest for the time being; who bore this name because his successor and representative, under whose inspection, direction, and authority, all the rest of the priests were, and whom they were to obey in all things: as the Lord God of Israel had commanded him;
to take care they should be done.
