5 Now Saul was coming from the field behind the oxen; and Saul said, "What is the matter with the people, that they are weeping?" So they told him the message from the inhabitants of Jabesh. 6 And the spirit of God came upon Saul in power when he heard these words, and his anger was greatly kindled. 7 He took a yoke of oxen, and cut them in pieces and sent them throughout all the territory of Israel by messengers, saying, "Whoever does not come out after Saul and Samuel, so shall it be done to his oxen!" Then the dread of the Lord fell upon the people, and they came out as one.
Matthew Henry's Commentary on 1 Samuel 11:5-7
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.
