1 Samuel 9:16

However, since the rank of kingship underlies all worth and power and rule, by this title the royal power of Christ is authoritatively and primarily indicated (for the anointing of kingship, as we learn in the historical books, comes first), and all the force of the other titles depends on that of royalty. For this reason, the person who knows the separate elements included under it also knows the power encompassing these elements. But it is the kingship itself which declares what the title of Christ means.

He is also described as a man coming from the land of Benjamin. He is called a man on account of the strength of his works; from the land of Benjamin, on account of his right confession of faith. Benjamin indeed means "son of the right hand." Who then is called this son of the right hand, if not he of whom it is written: "He ascended into heaven, and sits at the right hand of the Father" (Mark 16:19)? The land of Benjamin therefore is the holy Church. Because therefore the heretics have been expelled from this land, the king comes from the land of Benjamin, when one who is not polluted by any heresy but is catholic in faith receives the primacy of the holy Church. He enjoys the title of "man" if he is firm in faith and strong in action. He indeed is commanded to be anointed as leader over the people of the Lord: because the outward sacraments profit those priests who are not unworthy of the gifts of those same sacraments. Or priests are anointed when through the ministry of those who ordain them they receive an increase of spiritual graces. Whence it also follows: "He shall save my people from the hand of the Philistines." As anointed ones they can save others, because they have received spiritual graces more abundantly. For those who save the people are anointed over the people: because those who are appointed by the Lord to govern others receive the spiritual gifts of charisms by which they can benefit them; and they are superior in merits also to those whom they precede in rank. And because often a good pastor is chosen on the merit of a good people, it is well added: "Because I have looked upon my people." Likewise, because a good pastor must be sought from the Lord with great prayers, it is added: "Their cry has come to me." But perhaps some are troubled, because what is said here and what was said above seem contradictory. For there he says: "They have not rejected you, but me, that I should not reign over them, according to all their works which they have done from the day I led them out of the land of Egypt even to this day" (1 Kings 8:7). But now he says: "You shall anoint him leader over my people Israel, and he shall save my people from the hand of the Philistines, for I have looked upon my people, for their cry has come to me." Above, a king is permitted to be appointed as if by one who is angry; now he is appointed as if by one who is merciful…
