1 Kings 1:33-35

33And the king said unto them, Take with you the servants of your lord, and cause Solomon my son to ride upon mine own mule, and bring him down to Gihon: 34and let Zadok the priest and Nathan the prophet anoint him there king over Israel; and blow ye the trumpet, and say, Long live king Solomon. 35Then ye shall come up after him, and he shall come and sit upon my throne; for he shall be king in my stead; and I have appointed him to be prince over Israel and over Judah.
