1 Samuel 30:11

And they found an Egyptian man in the field, etc. The Catholic teachers hastening to engage in the battle with the heretics often find men abandoned by them, notable for the dark stain of their sins, unable to follow the teachers of error to devastate the Church due to the tenderness of their intellect; and they bring them to hear the Catholic faith, giving them the bread and water of the word; but they also add the sayings of preceding teachers, who, from the most beautiful tree of the present Church, as it were, from the fig tree, or severed at the brink of life and death, throughout the entire year of this current age which is now being lived, do not cease to preserve the mature memory of their teaching to refresh the souls of the faithful. And they well give a fragment of the dough, because they suggest not complete works to such people, but the sayings of the fathers deemed sufficient. They well give two clusters of grapes; because they show that they are to be united to Christ and the Church by the bonds of dual love.

The poor and the feeble, the blind and the lame, are called and come because the weak and the despised in this world are often quicker to hear the voice of God, as in this world they have nothing to delight them.The Egyptian servant of the Amalekites is a good example of this. When the Amalekites were plundering and moving about, he was left behind on the road sick and fainting from hunger and thirst. When David found him, he provided him with food and drink, and as soon as he revived he became David's guide, found the celebrating Amalekites, and with great bravery overthrew the people who had left him behind sick. Amalekite means "a people that laps." What does "a people that laps" signify but the hearts of the worldly? Going about after the things of earth, it is as if they are lapping them up when they take delight in temporal things alone. A lapping people takes plunder, so to speak, when out of its love for earthly things it heaps up profit from others' losses. The Egyptian servant is left behind on the road sick, because all sinners, once they begin to grow weak from the situation of this world, soon come to be despised by worldly minds. David found him and provided him with food and drink, because the Lord, who is "brave in hand" (if we attribute to him the meaning of David's name), does not despise what the world has cast aside. Often he directs to the grace of his love those who are not strong enough to follow the world, and who are, so to speak, left behind on the road, holding out to them the food and drink of his word. It is as if he chooses them as guides for himself on the road when he makes them his preachers. When they bring Christ to the hearts of sinners, it is as if they are leading David upon the enemy, and, like David, they strike the celebrating Amalekites with the sword, because by the Lord's power they overthrow all the proud who had despised them in the world.
