Suddenly - As before, at Gibeon Joshua 10:9, so now Joshua anticipates his enemies. Taken by surprise, and hemmed in between the mountains and the lake, the chariots and horses would have no time to deploy and no room to act effectively; and thus, in all probability, the unwieldy host of the Canaanites fell at once into hopeless confusion.

By the waters of Merom suddenly - Joshua, being apprised of this grand confederation, lost no time, but marched to meet them; and before they could have supposed him at hand, fell suddenly upon them, and put them to the rout.

So Joshua came, and all the people of war with him, against them,.... Being encouraged by the Lord, they set out with Joshua at the head of them, to fight the kings and their forces. It is highly probable that these were not the whole body of armed men in the camp of Israel, but a select company Joshua took of them, and who would be able to make quicker marches on this expedition:

by the waters of Merom suddenly; the Targum is,"they lay by the waters of Merom;''as they were thoughtless and careless, and not on their guard, Joshua and his forces came to them suddenly, unawares, and they not provided for them:

and they fell upon them; at once, which threw them into disorder and confusion.

With this to inspirit them, the Israelites fell upon the enemy and smote them, chasing them towards the north-west to Sidon, and westwards as far as Misrephothmaim, and into the plain of Mizpah on the east. Sidon is called the great (as in Joshua 19:28), because at that time it was the metropolis of Phoenicia; whereas even by the time of David it had lost its ancient splendour, and was outstripped by its daughter city Tyre. It is still to be seen in the town of Saida, a town of five or six thousand inhabitants, with many large and well-built houses (see Rob. Pal. iii. p. 415, and Movers, Phnizier, ii. 1, pp. 86ff.). Misrephothmaim (mentioned also at Joshua 13:6), which the Greek translators have taken as a proper name, though the Rabbins and some Christian commentators render it in different ways, such as salt-pits, smelting-huts, or glass-huts (see Ges. Thes. p. 1341), is a collection of springs, called Ain Mesherfi, at the foot of the promontory to which with its steep pass the name of Ras el Nakhra is given, the scala Tyriorum or Passepoulain of the Crusaders (see V. de Velde, Mem. p. 335, and Ritter, Erdk. xvi. p. 807). מצפּה בּקעת (Eng. Ver. "the valley of Mizpeh") is probably the basin of the Huleh lake and of Nahr Hasbany, on the western side of which lay the land of Mizpah (Joshua 11:3).

So Joshua came, and all the people of war with him, against them by the waters of Merom suddenly; and they fell upon them.

11:7 Suddenly - When they least expected them, intending there to refresh, and prepare, and order themselves for the offensive war which they designed.

11:1-9 The wonders God wrought for the Israelites were to encourage them to act vigorously themselves. Thus the war against Satan's kingdom, carried on by preaching the gospel, was at first forwarded by miracles; but being fully proved to be of God, we are now left to the Divine grace in the usual course, in the use of the sword of the Spirit. God encouraged Joshua. Fresh dangers and difficulties make it necessary to seek fresh supports from the word of God, which we have nigh unto us for use in every time of need. God proportions our trials to our strength, and our strength to our trials. Joshua's obedience in destroying the horses and chariots, shows his self-denial in compliance with God's command. The possession of things on which the carnal heart is prone to depend, is hurtful to the life of faith, and the walk with God; therefore it is better to be without worldly advantages, than to have the soul endangered by them.
