Musar על בראשית 43:30

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.
