There is a play upon the word, three times repeated, which means both "an ass" and also "a heap." The spirit of riddle-making Judges 14:12, Judges 14:18 is apparent in this song of triumph (compare Judges 5:1; Exodus 15:1; 1 Samuel 18:6-7).

And Samson said,.... In a kind of triumphant song:

with the jawbone of an ass, heaps upon heaps; that is, with such an instrument he had slain heaps of men, who lay dead in heaps upon one another; in the words for an "ass", and for an "heap", is an elegant "paronomosia", not easy to be expressed in our language:

with the jaw of an ass have I slain a thousand men: this he said not in a proud and haughty manner, ascribing it to himself, as Josephus suggests (m), since he takes notice of the mean instrument he used; which showed that he was sensible it was not done by his own power, but by the power of God, which enabled him by such weak means to do such wonderful things.

(m) Antiqu. l. 5. c. 8. sect. 9.

And Samson said, With the jawbone of an ass, heaps upon heaps, with the jaw of an ass have I slain a thousand men.

15:16 Slain a thousand men - What could be too hard for him to do, on whom the Spirit of the Lord came mightily? It was strange the men of Judah did now at least come in to his assistance. But he was to be a type of him, who trod the wine - press alone.

heaps upon...: Heb. an heap, two heaps

16. With the jawbone of an ass, heaps upon heaps, with the jaw of an ass have I slain a thousand men-The inadequacy of the weapon plainly shows this to have been a miraculous feat, "a case of supernatural strength," just as the gift of prophecy is a case of supernatural knowledge [Chalmers].

15:9-17 Sin dispirits men, it hides from their eyes the things that belong to their peace. The Israelites blamed Samson for what he had done against the Philistines, as if he had done them a great injury. Thus our Lord Jesus did many good works, and for those the Jews were ready to stone him. When the Spirit of the Lord came upon Samson, his cords were loosed: where the Spirit of the Lord is, there is liberty, and those are free indeed who are thus set free. Thus Christ triumphed over the powers of darkness that shouted against him, as if they had him in their power. Samson made great destruction among the Philistines. To take the bone of an ass for this, was to do wonders by the foolish things of the world, that the excellency of the power might be of God, not of man. This victory was not in the weapon, was not in the arm; but it was in the Spirit of God, which moved the weapon by the arm. We can do all things through Him that strengtheneth us. Seest thou a poor Christian, who is enabled to overcome a temptation by weak, feeble counsel, there is the Philistine vanquished by a sorry jaw-bone.
