Kabbalah sur La Genèse 31:44

Therefore, it is proper for a man to fulfill the godly work and be trusted with it like a pillar that doesn’t shake, and likewise the word Brit means ‘fulfilling’ like what it says “Come now, let us make a covenant, you and I” (Genesis 31:44). Therefore, one who wants to merit the attribute of ‘Tzadik’ must be strong and trusted in his work, and about this is said “Whoever keeps a precept will know no evil thing (Ra)” (Ecclesiastes 8:5); and you already know based on what was said before what “Ra” (evil) means.
