1 Kings 1:50-53

50And Adonijah feared Solomon, and he got up and went [to the tabernacle on Mt. Zion] and took hold of the horns of the altar [seeking asylum].

51Now Solomon was told, “Behold, Adonijah is afraid of King Solomon, and behold, he has grasped the horns of the altar [seeking God’s protection], saying, ‘King Solomon must swear to me today that he will not kill his servant with the sword.’ ”

52Solomon said, “If he [proves he] is a worthy man, not even one of his hairs shall fall to the ground; but if wickedness is found in him, he shall die.”

53So King Solomon sent [soldiers], and they brought Adonijah down from the altar [that was in front of the tabernacle]. And he came and bowed down to King Solomon, and Solomon said to him, “Go to your house.”
