Bible Notes Online - Judges 7 - ESV
Commentary

v1-3: Gideon had gathered his army for attacking the Midianites, see 6.35. We note that the Midianite army was very large; 6.5; 7.12; 8.10.

The Lord God insisted that His work be done in His way, that His power be demonstrated. Gideon had to ask if anyone was fearful; 22,000 men left (Deut 20.5-9); there was need for single-mindedness.

v4: God tested Gideon, by further sifting the army. This was part of God's teaching and moulding of Gideon.

v5-8: Gideon took the men to a stream; those who put their heads to the water were sent home. Only those who used their hands were chosen; they indicated a readiness and alertness.

v9-12: Lest the reduction in the size of his army should discourage him, the Lord sent a further encouragement to Gideon, but he had to go to the Midianite camp to receive it.

v13-14: The man's dream was about a loaf of barley; lit. "rolling roughness"; this was ironic since Midian had destroyed all the barley (6.3-6), yet it would be a barley loaf, in the person of Gideon (the "destroyer"). The loaf was sent, just as Gideon was sent by God, it was not his own scheme.

v15: Not surprisingly, Gideon was encouraged by the dream; he confidently roused his men for battle and victory. They awoke, and attacked during the night, as the guard was changing (v19).

v16-18: Trumpets were provided, as in the victory at Jericho a century or more earlier; see 2 Cor 4.7; the treasure was in earthen vessels, both men and pots, that the glory might be God's.

v19-22: While Israel remained around the camp, in three small groups (v16), the Midianites were thrown into panic.

v23: Other Israelites joined the fray, presumably from among the thousands who had earlier been sent home. As Midian was scattered, more soldiers were needed to pursue them. Soldiers from Ephraim joined also. This is significant, since chapter 8 relates their complaint against Gideon.
