מוסר אויף בראשית 43:30

SINCE this quality is of a kind with the nature of the Creator, may He be greatly praised and mightily exalted, it is complementary to the twelve attributes especially characteristic of Him, i.e., the thirteen qualities which are ascribed to the Lord of Worlds, viz., "The Lord eternal is a merciful and gracious God," and so forth. That which it is possible for the wise man to aim at in action is, being slow to anger, "long-suffering," and largely generous, as it is said, "abundant in loving-kindnesses," tolerant of sin, as it is said, "Forgiving iniquity," and so forth. The upright and wise man must emulate these as far as he is able to do. Even as man desires that he be dealt with mercifully, when compelled to seek help, so must he be merciful to whosoever seeks his help. This quality is extremely praiseworthy, and God, exalted may He be, has distinguished His righteous servants through their love therefor. As thou knowest of Joseph, where it is said (Gen. xliii. 30), "His bowels did yearn upon his brother." The intelligent man has the qualities of pity and compassion implanted in his soul and ever present therein.

The Creator, may He be Blessed, apportioned this quality to the righteous and to His servants so that through this quality they might be identified, as you learn in the case of Joseph, "whose mercies were kindled" (Gen. 43:30). And it is fitting for the intelligent person that the quality of Mercy and Graciousness should be firmly fixed and present in his heart at all times.
