לֵ֣ב שָׂ֭מֵחַ יֵיטִ֣ב פָּנִ֑ים וּבְעַצְּבַת־לֵ֝ב ר֣וּחַ נְכֵאָֽה׃
Un cœur joyeux rend le visage serein; le cœur souffre-t-il, l’esprit est abattu.
Rashi
A merry heart makes a cheerful face If you cheer up the heart of the Holy One, blessed be He, by following His ways, He will show you a cheerful face to do your will, but if you sadden Him, He will show you a breaking spirit, as it is stated (Gen. 6:6f): “And He became saddened to His heart. And the Lord said, ‘I will erase man, etc.’“ a breaking spirit (Talant in Old French, explained in Ecc. 1:6) a spirit of fury.
