Shofetim 20:38-40

Orthodox Jewish Bible

³⁸ Now there was a mo’ed (appointed agreement) between the Ish Yisroel and the ones ambushing, that they should make a great flame with smoke rise up out of the Ir.

³⁹ And when the Ish Yisroel turned in the milchamah, Binyamin began to inflict casualties on the Ish Yisroel about sheloshim ish; for they said, Surely they are defeated before us, as in the milchamah harishonah.

⁴⁰ But when the smoke cloud began to arise up out of the Ir with an ammud ashan (pillar of smoke), Binyamin looked behind them, and, hinei, the whole Ir ascended up in smoke to Shomayim.
