Shmuel Bais 16:11-12

And Dovid said to Avishai, and to all his avadim, Hinei, beni, which came forth from within me, seeketh my nefesh; how much more now may this Ben-HaYemini (Benjamite) do it? Let him alone, and let him curse; for HASHEM hath bidden him. It may be that HASHEM will look on mine affliction, that HASHEM will repay me tovah for his cursing this day.
