And when he numbered them in Bezek, the children of Israel were three hundred thousand, and the men of Judah thirty thousand.

Wesley's Notes

11:8 Men of Judah - Who are numbered apart to their honour, to shew how readily they, to whom the kingdom was promised, Gen 49:10, submitted to their king, though of another tribe; and how willing they were to hazard themselves for their brethren although they might have excused themselves from the necessity of defending their own country from their dangerous neighbours the Philistines.

Jamieson-Fausset-Brown Bible Commentary

8. Bezek-This place of general muster was not far from Shechem, on the road to Beth-shan, and nearly opposite the ford for crossing to Jabesh-gilead. The great number on the muster-roll showed the effect of Saul's wisdom and promptitude.

Matthew Henry's Concise Commentary

11:1-11 The first fruit of Saul's government was the rescue of Jabesh-gilead from the Ammonites. To save their lives, men will part with liberty, and even consent to have their eyes put out; is it then no wisdom to part with that sin which is as dear to us as our right eye, rather than to be cast into hell-fire? See the faith and confidence of Saul, and, grounded thereon, his courage and resolution. See also his activity in this business. When the Spirit of the Lord comes upon men, it will make them expert, even without experience. When zeal for the glory of God, and love for the brethren, urge men to earnest efforts, and when God is pleased to help, great effects may speedily be produced.
