And put oil on them as you did on their father, so that they may be my priests: the putting on of oil will make them priests for ever, from generation to generation.
These you are to put on Aaron, your brother, and on his sons, putting oil on them, separating them and making them holy, to do the work of priests to me.
And put the linen bands round Aaron and his sons, and the head-dresses on them, to make them priests by my order for ever: so you are to make Aaron and his sons holy to me.
And by this agreement, he and his sons after him have the right to be priests for ever; because, by his care for the honour of his God, he took away the sin of the children of Israel.
