It was told Shlomo, saying, Behold, Adoniyahu fears king Shlomo; for, behold, he has laid hold on the horns of the altar, saying, Let king Shlomo swear to me first that he will not kill his servant with the sword.
The news came to Yo'av; for Yo'av had turned after Adoniyahu, though he didn't turn after Avshalom. Yo'av fled to the Tent of the LORD, and caught hold on the horns of the altar.
Aharon shall make atonement on its horns once in the year; with the blood of the sin offering of atonement once in the year he shall make atonement for it throughout your generations. It is most holy to the LORD.*
