1 Samuel 9:5

But when they came to the land of Zuph, Saul said to his servant, etc. From the fifth place of failed inquiry, Saul intends, as it were, to return. And the Lord seemed, due to the enormity of human transgression, as if he wished to turn back from caring for the salvation of the impious, when, in the fifth age of the world, the oracles of the prophets were withdrawn, the frequent communication with angels was withdrawn, and only the wicked deeds of depraved men increased. And indeed, the world was pressed by so many and such great crimes before the coming of the Lord, that the Creator of the human race seemed to be more concerned with protecting the just than acquiring the salvation of the impious. However, for the sake of the adversities of his chosen ones, the provident Creator wished both to prove the invincible patience and to sharpen desires by deferral more and more; therefore it follows:

But while holy men cannot convert others through their preaching, they begin to fear intensely for themselves—lest they displease Almighty God in the very thing by which they thought they were greatly pleasing Him. And it often happens that the hearts of new preachers are so frightened that they now resolve to abandon the office of preaching itself and to devote themselves to God through silence. He deliberates about returning to his father who, having set aside the intention of preaching, desires to be free for God in the secret of silence. He is said to return who is reported to have been sent before. For the sons are, as it were, in the presence of their father when chosen men linger in the secret contemplation of the Redeemer. They return, therefore, when from the public work of holy preaching they come to search out the joys of eternal brightness. But because holy men do nothing without counsel, Saul consulted the boy about the return to his father. For we consult the boy when with attentive mind we take care that what we attempt to arrange should not differ from spiritual understanding. Indeed, he had resolved to return to his father who said: "I said, I will guard my ways, that I may not sin with my tongue. I set a guard over my mouth, when the sinner stood against me" (Psalm 38:1–2). The sinner stands against the preachers when, in response to their preaching, he does not abandon the state of his iniquity. And because the preacher then proposes to be silent toward him and to be free for God, so that he may return to the Father, he becomes mute. But because through silence he better learned the will of God, his heart grew warm, and with the fire of inward meditation blazing forth, he spoke. This is shown also in this passage, because the boy, when consulted, bestows counsel upon the one consulting him, saying: "Behold, there is a man of God in this city, a noble man; everything he says comes to pass without ambiguity. Now therefore let us go there; perhaps he will show us our way for which we have come."
