1 Samuel 9:19

And Samuel answered Saul, saying: I am the seer, etc. John responded, with the Lord bestowing heavenly gifts upon him, saying: I am the friend of the Bridegroom; I am your forerunner; I ought to be baptized by you, who, coming before me, have been made ahead of me. And indeed you will now receive baptism from me with the people of believers, together we will serve the feast of the word, and in turn, we are refreshed by the faith of the listeners. But when the splendor of your grace has shone upon all, with my role as forerunner completed, I will leave you to preach, and having joined the chorus of preceding prophets, I will take care to reveal all the mysteries of your temporal dispensation to the crowds of the faithful, indeed your members.

Therefore it is also added: "And Samuel answered Saul, saying: I am the Seer. But go up before me to the high place today, that you may eat with me, and I will send you away in the morning." What does it mean to say, "I am the Seer," except to show himself humble, as he appeared to their eyes? As if to say: In your estimation, the one you seek is great, but the one you see is small. For in this word, "Seer," it is not a title of praise, but "I am." As if to say: That Seer is I—not what you suppose, but what you behold. But he who knew how to humble himself knew how to give gifts not as one who is lowly, but as one who is exalted. For this reason he also commands him to go up before him to the high place, so that he might eat with him. He ascends to the high place who raises his mind to know higher things. Indeed, to ascend to the high place is to prepare the heart for understanding lofty matters. Hence Peter too is taken up on the mountain, so that he might deserve to see the glory of the transfigured Redeemer (Matt. 17:1). For in that ascent of the mountain, the lofty preparation of the mind is expressed: because he who does not fix his mind on high things through earnest attention will not be able to see exalted things. Since, therefore, we better understand sublime things when we are prepared, Saul is commanded to go up to the high place before Samuel. For we ascend, as it were, to the high place before the preacher when we first direct our mind to know lofty things, and they afterwards speak to us of those very things to which we have directed our attention. But what does it mean when he says, "That you may eat with me today"? When holy preachers speak of heavenly things, they refresh the hearts of their chosen hearers: for as the Truth attests, the food of the soul is the word of God: "Man does not live by bread alone, but by every word that proceeds from the mouth of God" (Matt. 4:4). For bread is the nourishment of the body; the word is the nourishment of the mind. But those who refresh the body without the mind are dead in mind, alive in flesh. Hence Paul also says of the self-indulgent widow: "She who lives in pleasure is dead while she lives" (1 Tim. 5:6). For the widow would not die through the delights of food if she satisfied her soul with the food of God's word, since Paul himself says: "Nothing is unclean that is received with thanksgiving"…
