Yehoshua 8:20

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.

Yehoshua 8:20 Meaning and Commentary

Joshua 8:20

And when the men of Ai looked behind them
On some account or another, perhaps observing that the army of Israel made a full stop and was gazing at the city:

they saw, and, behold, the smoke of the city ascended up to heaven;
from whence they concluded an enemy was there, and had set fire to it:

and they had no power to flee this way or that way;
for if they turned back to their city there was an enemy, how powerful they knew not, possessed of it, and whom they might expect would meet them; and if they pushed forward, there was the whole army of Israel against them, which now turned and faced them, showing no fear of them:

and the people that fled to the wilderness turned back upon the
pursuers;
the people of Israel, that fled by the way of the wilderness, ( Joshua 8:15 ) , turned about, and fell upon the men of Ai that pursued them.

Yehoshua 8:20 In-Context

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.

21 And when Yehoshua and kol Yisroel saw that the ambush had taken the Ir, and that the ashan HaIr ascended, then they turned again, and attacked the anshei HaAi.

22 Then these came out of the Ir against them; so they were in the midst of Yisroel, some on this side, and some on that side; and they struck them down, until they left none of them sarid (remnant, survivor) or palit (refugee, fugitive).
