1Sam 12:4

“Because indeed he had been known by all for such great contempt of worldly things, there follows: 'And they said: You have not falsely accused us, nor oppressed us, nor taken anything from anyone's hand. And he said to them: The Lord is witness against you, and His Christ is witness on this day, that you will not find anything in my hand. And they said: He is witness.' In this passage it should be noted that the holy man did not speak of the good things he had done, but rather set forth the evil things he had not done; so that by keeping silent he might preserve his good deeds for eternal rewards, and by speaking he might not lose the fragrance of his good reputation. Paul indeed speaks, saying: "We are the good fragrance of Christ in every place" (II Cor. 2:15). He also, rebuking certain people, says: "The name of God is blasphemed among the Gentiles because of you" (Rom. 2:24). Likewise he admonishes his disciple, saying: "A bishop must also have a good testimony from those who are outside" (I Tim. 3:7). Therefore, when he so carefully affirmed that he had avoided evil, and kept silent about the great good deeds he had performed, the blessed man openly showed on what a summit of virtues he stood, since by condemning evil he preserved the fragrance of good reputation as an example for the elect, and by concealing his works of virtue, he safeguarded the rewards of eternal recompense.”
