Joab had supported Adonijah, but not Absalom. But when Joab heard what happened to Abiathar, he was frightened and ran to the tent of the Lord to hold onto the horns of the altar.
He made a horn for each of the four corners of the altar. He joined each horn to its corner so that everything was one piece. He covered the altar with bronze.
“Once a year Aaron must make a special sacrifice. He will use the blood of the sin offering to erase the sins of the people. He will do this at the horns of this altar. This day will be called the Day of Atonement, and it will be a very special day for the Lord.”
Then someone told Solomon, “Adonijah is afraid of you, King Solomon. He is at the Holy Tent holding onto the horns of the altar, and he refuses to leave. Adonijah says, ‘Tell King Solomon to promise that he will not kill me.’”
