1 Kings 1:33-35

33 And the king said to them, Take with you the servants of your lord, and put Solomon my son on my beast, yes, mine, and take him down to Gihon;

34 And there let Zadok the priest and Nathan the prophet put the holy oil on him to make him king over Israel; and sounding the horn say, Long life to King Solomon!

35 Then come up after him and he will come in and take his place on the seat of my kingdom; for he is to be king in my place, and I have given orders that he is to be ruler over Israel and over Judah.
