כָּאֵב(b. h.) to be heavy, to feel pain. Y.Sabb.IX, 17a ib. XIX, 17a bot. (ref. to Gen. 34:25) בהיותו כּוֹאֵב … כל איבריהם כּוֹאֲבִים עליהם it does not say, ‘when it (the wound) was painful, but …, which intimates that all their limbs pained them. Hif. הִכְאִיב to cause pain, grief. Ex. R. s. 3 (ref. to Ex. 3:7) ידעתי … להַכְאִיבֵנִיוכ׳ I know how much they will grieve me Pirké dR. El. ch. XII שלא להַכְאִיבוֹ so as to make him feel no pain. Midr. Till. to Ps. 94 (ref. to Prov. 3:12) א״ת וּכְאָב אלא וּכְאֵב … שמַכְאִיבוֹ read not ukhab (and like a father) but ukheb (and pain), when He sends him pain.
