'Horns' in the Bible

And Adonijah was afraid of Solomon, and he arose, went and took hold of the horns of the altar.

Now it was told Solomon, saying, “Behold, Adonijah is afraid of King Solomon, for behold, he has taken hold of the horns of the altar, saying, ‘Let King Solomon swear to me today that he will not put his servant to death with the sword.’”

Now the news came to Joab, for Joab had followed Adonijah, although he had not followed Absalom. And Joab fled to the tent of the Lord and took hold of the horns of the altar.

Then Zedekiah the son of Chenaanah made horns of iron for himself and said, “Thus says the Lord, ‘With these you will gore the Arameans until they are consumed.’”
