30 And the Lord delivered it into the hands of Israel: and they took it, and its king, and slew the inhabitants with the edge of the sword, and every thing breathing in it; and there was not left in it any that survived and escaped; and they did to its king, as they did to the king of Jericho.

Joshua 10:30 Meaning and Commentary

Joshua 10:30

And the Lord delivered it also, and the king thereof, into
the hand of Israel
At once, no opposition being made that we read of:

and he smote it with the edge of the sword, and all the souls that
[were] therein, he let none remain in it;
that is, Israel smote it, or Joshua, and indeed both; and this was according to the orders given them to be observed with respect to all the cities and nations of Canaan; and that because of their abominable sins and wickedness, and to make way and room for the people of Israel, ( Deuteronomy 7:1 Deuteronomy 7:2 ) ;

but did unto the king thereof as he did unto the king of Jericho:
slew him with the inhabitants.
