Judges 20:40

40 and they saw as a pillar of smoke go up from the city. And also Benjamin beholding behind, when he saw his city taken, and the flames be borne on high, (yea, the Israelites saw the pillar of smoke go up from the city. And then the Benjaminites looking behind, also saw that their city had been taken, and the flames of it to be borne up on high.)

Judges 20:40 Meaning and Commentary

Judges 20:40

But when the flame began to arise up out of the city with a
pillar of smoke
Fire being set to it by the liers in wait, who had entered it, and who made a large fire, which caused a vast pillar of flame and smoke to arise, which might be seen a great way off:

the Benjamites looked behind them;
perhaps at hearing the blowing of the trumpet, and the long sound of that:

and, behold, the flame of the city ascended up to heaven;
went upwards, and reached to a great height.

Judges 20:40 In-Context

38 Soothly the sons of Israel had given a sign to them which they had set in ambushments, that after that they had taken the city, they should kindle (a) fire, and that by smoke ascending on high, they should show the city (to be) taken. (And the Israelites had arranged a sign, or a signal, from those whom they had set in ambush, which was that after they had taken the city, they would kindle a fire, and that by the smoke going up on high, they would show that the city had been taken.)

39 And when the sons of Israel set in that battle saw this; for the sons of Benjamin guessed them to flee, and they followed busilier, when thirty men of their host were slain; (And so the Israelites set in the battle saw this; but the Benjaminites guessed them to flee, and they followed them more busily, for they had already killed thirty Israelites;)

40 and they saw as a pillar of smoke go up from the city. And also Benjamin beholding behind, when he saw his city taken, and the flames be borne on high, (yea, the Israelites saw the pillar of smoke go up from the city. And then the Benjaminites looking behind, also saw that their city had been taken, and the flames of it to be borne up on high.)

41 they that feigned to flee before, turned their face to Benjamin, and more strongly withstood him. And when the sons of Benjamin had seen this thing, (And then they who had feigned to flee before, now turned their faces to the Benjaminites/now turned to face the Benjaminites, and strongly stood against them. And when the Benjaminites had seen this,)

42 they were turned into flight, and they began to go to the way of desert; while also adversaries pursued them there; but also they, that had burnt the city, came against them. (they turned to flight, yea, to run away, and they started on the way to the wilderness; but their adversaries pursued them there; and then also they, who had burned down the city, came out against them.)
