The kings came and fought, then fought the kings of Canaan in Taanach by the waters of Megiddo; they took no gain of money. The kings came and fought - It is conjectured that Jabin and his confederates had invaded Manasseh, as both Taanach and Megiddo were in that tribe: and that they were discomfited by the tribes of Zebulun and Naphtali at Taanach and Megiddo; while Barak defeated Sisera at Mount Tabor.
They took no gain of money - They expected much booty in the total rout of the Israelites; but they were defeated, and got no prey; or, if applied to the Israelites, They fought for liberty, not for plunder.
