창세기 48:2의 Musar

ויתחזק ישראל וישב על המטה . Israel's ability to strengthen himself and sit on "the bed," was due to "his bed" being שלימה. Hail to anyone who merits it. Every pious person constantly prays that he will not be the cause of any פסול, defect, among his children or children's children. All that man can leave behind in this world are children and grandchildren who by their own righteousness bear testimony to the piety of their fathers.
