| Gill's Exposition of the Entire Bible And there came against Gibeah ten thousand chosen men out of all Israel,.... Which, according to Ben Gersom, were the liers in wait; and came from the south, as the Targum says: and the battle was sore; not between those liers in wait, and the Benjaminites, but between those at Baaltamar, and them who set themselves in battle array against them, and they fought stoutly on both sides: but they knew not that evil was near them; that there was an ambush laid, by which they were in great danger; they knew nothing of the 10,000 men that were now come out against Gibeah, and were between them and that.
Keil and Delitzsch Biblical Commentary on the Old TestamentThrough the advance of the ambush there came 10,000 picked men of all Israel "from opposite to Gibeah" (who now attacked in the rear the Benjaminites who were pursuing the flying army of Israel); "and the contest became severe, since they (the Benjaminites) did not know that the calamity was coming upon them."
Geneva Study BibleAnd there came against Gibeah ten thousand chosen men out of all Israel, and the battle was sore: but they knew not that {q} evil was near them. (q) They did not know that God's judgment was at hand to destroy them.
Wesley's Notes 20:34 Chosen men - Selected out of the main body, which was at Baal - tamar; and these were to march directly to Gibeah on the one side, whilst the liers in wait stormed it on the other side, and whilst the great body of the army laboured to intercept the Benjamites, who having pursued the Israelites that pretended to flee, now endeavoured to retreat to Gibeah.
Jamieson-Fausset-Brown Bible Commentary34. there came against Gibeah ten thousand chosen men-This was a third division, different both from the ambuscade and the army, who were fighting at Baal-tamar. The general account stated in Jud 20:35 is followed by a detailed narrative of the battle, which is continued to the end of the chapter.
Matthew Henry's Concise Commentary17:7-13 Micah thought it was a sign of God's favour to him and his images, that a Levite should come to his door. Thus those who please themselves with their own delusions, if Providence unexpectedly bring any thing to their hands that further them in their evil way, are apt from thence to think that God is pleased with them. |
