Commentaire sur Les Proverbes 13:13

He who despises a thing will be pledged to it Heb. יחבל. He who despises one of the words of the Torah will ultimately be taken for it as a pledge.

but he who reveres a commandment will be rewarded lit. will be paid. He will receive a reward. Midrash Tehillim expounds: “He who despises a thing will be pledged to it” concerning David, who said before the Holy One, blessed be He, “Of what use are the madmen that You created?” He replied, “By your life, you will ultimately need madness.” When he came before Achish to feign madness, “and he let his saliva run down upon his beard, etc.” (I Sam. 21:14).
