11 But before dawn the next morning, Saul arrived, having divided his army into three detachments. He launched a surprise attack against the Ammonites and slaughtered them the whole morning. The remnant of their army was so badly scattered that no two of them were left together.
Matthew Henry's Commentary on 1 Samuel 11:11
Commentary on 1 Samuel 11:1-11
(Read 1 Samuel 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.
