1Sam 21:1

“In similar fashion, whenever we have God on our side, even if we are utterly alone, we will live more securely than those who dwell in the cities. After all, the grace of God is the greatest security and the most impregnable fortification. To prove to you how the person who, in fact, lives utterly alone turns out to be more secure and efficacious than a person living in the middle of cities and enjoying plenty of human assistance, let us see how David, though shifting from place to place and living like a nomad, was protected by the hand from above, whereas Saul, who in fact was in the middle of cities and had armies at his command, bodyguards and shieldbearers as well, still spent each day in fear and dread of enemy assaults. Whereas the one man, although alone and with no one else in his company, had no need of assistance from human beings, the other, by contrast, needed his help, despite wearing a diadem and being clad in purple. The king stood in need of the shepherd; the wearer of the crown had need of the peasant.”

“And Achimelech was astonished, etc. The ancient chosen ones were astonished, and the modern ones are astonished too, whenever they receive the coming of the Lord's visitation with a simple mind. They are not only stunned by the majesty of His vision, but also disturbed by the rarity of those who desire to follow the grace of such great piety. For it is said: Why are you alone, and no one with you? As it is said elsewhere: My escape has perished, and there is no one who seeks my soul (Psalm 141). Though it is certain that during the time of the passion, many saints, although very few compared to the crowd of persecutors, lovingly sought the soul of Christ. But just as where it was not among them, of those whose snares are set for me, those who seek the soul of Christ (Psalm 34), so here there was none of those who expelled Christ who followed the faith of Christ. And elsewhere, when he says: All have turned aside, they have together become worthless; there is none who does good, not even one (Psalm 13). To show that he meant not all men entirely, but all of those who were to be spoken about, he added further and said: They devour my people as they devour bread: they do not call upon the Lord, they trembled with fear where there was no fear, because God is in the generation of the righteous. And in the Gospel the Lord says: Unless a grain of wheat falls into the earth and dies, it remains alone; but if it dies, it bears much fruit (John 12). It is known that the same grain before the passion of its death had many faithful followers. But it is said to be alone without the company of those who were previously unbelievers who were to be called to faith through the same passion. Why then, he says, are you alone, and no one with you? Why are you alone, that is, with your faithful members, and none outside the predetermined number by the Father could be saved from such a multitude? This is said more with astonishment than for the chosen ones to speak by reasoning against proud counsel.”
