1. Who fought against them. The power of the enemy must be taken notice of, that the victory may appear the more glorious. Jabin and Sisera had been mentioned in the history, but here it appears further, (1.) That Amalek was in league with Jabin, and sent him in assistance, or endeavoured to do it. Ephraim is here said to act against Amalek (v. 14), probably intercepting and cutting off some forces of the Amalekites that were upon their march to join Sisera. Amalek had helped Moab to oppress Israel (ch. iii. 13) and now had helped Jabin; they were inveterate enemies to God's people—their hand had always been against the throne of the Lord (Exod. xvii. 16); and therefore they were the more dangerous. (2.) That others of the kings of Canaan, who had somewhat recovered themselves since their defeat by Joshua, joined with Jabin, and strengthened his army with their forces, having the same implacable enmity to Israel that he had, and those kingdoms, when they were in their strength, having been subject to that of Hazor, Josh. xi. 10. These kings came and fought, v. 19. Israel had no king; their enemies had many, whose power and influence, especially acting in confederacy, made them very formidable; and yet Israel, having the Lord for their King, was too hard for them all. It is said of these kings that they took no gain of money, they were not mercenary troops hired into the service of Jabin (such often fail in an extremity), but they were volunteers and hearty in the cause against Israel: they desired not the riches of silver, so the Chaldee, but only the satisfaction of helping to ruin Israel. Acting upon this principle, they were the more formidable, and would be the more cruel.
