1 Kings 1:28-34

28Then king David answered and said, Call me Bathsheba. And she came into the king’s presence, and stood before the king.1 29And the king swore, and said, As the LORD liveth, that hath redeemed my soul out of all distress, 30Even as I swore to thee by the LORD God of Israel, saying, Assuredly Solomon thy son shall reign after me, and he shall sit upon my throne in my stead; even so will I certainly do this day. 31Then Bathsheba bowed with her face to the earth, and did reverence to the king, and said, Let my lord king David live for ever.

32And king David said, Call me Zadok the priest, and Nathan the prophet, and Benaiah the son of Jehoiada. And they came before the king. 33The king also said to them, Take with you the servants of your lord, and cause Solomon my son to ride upon my own mule, and bring him down to Gihon:2 34And let Zadok the priest and Nathan the prophet anoint him there king over Israel: and blow ye with the trumpet, and say, God save king Solomon.
