1 Kings 1:33-35

33the king said to them: “Take with you the servants of your lord, and have my son Solomon ride on my own mule, and bring him down to Gihon.

34There let Zadok the kohen and Nathan the prophet anoint him as king over Israel, blow the shofar and say: ‘Long live King Solomon!’

35Then you shall come up after him, and he shall come and sit on my throne. For he shall be king in my place, as I have appointed him to be ruler over Israel and Judah.”
