Iyov 31:28-30

Orthodox Jewish Bible

²⁸ This also were an avon to be punished by the judge; for then I would have been unfaithful, denying El that is on high.

²⁹ If I rejoice at the misfortune of him that hated me, or gloated when rah found him,

³⁰ Neither have I allowed my mouth to sin by invoking a curse to his nefesh.
