1 Kings 1:38-39

So Zadok the priest, Nathan the prophet, and Benaiah son of Jehoiada left with the Kerethites and Pelethites. They put Solomon on King David’s mule and took him to the spring called Gihon. Zadok the priest took the container of olive oil from the Holy Tent and poured the oil on Solomon’s head to show he was the king. Then they blew the trumpet, and all the people shouted, “Long live King Solomon!”
