³⁹ And the men of Israel turn in battle, and Benjamin hath begun to smite the wounded among the men of Israel, about thirty men, for they said, `Surely they are utterly smitten before us, as [at] the first battle;

⁴⁰ and the volume hath begun to go up from the city -- a pillar of smoke -- and Benjamin turneth behind, and lo, gone up hath the perfection of the city toward the heavens.
