And they gave Solomon word of it, saying, See, Adonijah goes in such fear of King Solomon, that he has put his hands on the horns of the altar, saying, Let King Solomon first give me his oath that he will not put his servant to death with the sword.
And news of this came to Joab; for Joab had been one of Adonijah's supporters, though he had not been on Absalom's side. Then Joab went in flight to the Tent of the Lord, and put his hands on the horns of the altar.
And once every year Aaron is to make its horns clean: with the blood of the sin-offering he is to make it clean once every year from generation to generation: it is most holy to the Lord.
