Matthew Henry on 1 Samuel 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.

They now honoured Saul whom they had despised; and if an enemy be made a friend, that is more to our advantage than to have him slain. The once despised Saviour will at length be acknowledged by all as the Lord's own anointed king. As yet, upon his mercy-seat, he receives the submission of rebels, and even pleads their cause; but shortly, from his righteous tribunal, he will condemn all who persist in opposing him.
