JDG 15:16

16 and he said, With the cheek[[bone]] of an ass, that is, with the nether cheek[[bone]]of a colt of she-asses, I have done away Philistines, and I have killed therewith a thousand men. (and he said, With the jawbone of a donkey, that is, with the lower jawbone of the colt of a female donkey, I have done away the Philistines, and I have killed a thousand men with it.)
