Yehoshua 8:18-20

Orthodox Jewish Bible

¹⁸ And Hashem said unto Yehoshua, Stretch out the kidon (javelin) that is in thy yad toward Ai; for I will give it into thine yad. And Yehoshua stretched out the kidon that he had in his yad toward the Ir.

¹⁹ And the ambush arose quickly out of their makom, and they ran as soon as he had stretched out his yad; and they entered into the Ir, and took it, and hastened and set eish to the Ir.

²⁰ And when the men of Ai looked behind them, they saw, and, hinei, the ashan HaIr (smoke of the city) ascended up to Shomayim, and they had no way to flee here or there; and HaAm that fled to the midbar turned back upon the pursuers.
