John Gill's Bible Commentary Ver. 9. And they said unto the messengers that came , etc.] From Jabeshgilead, that is, Saul and Samuel said to them, as follows: thus shall ye say unto the men of Jabeshgilead : when they returned unto them, as they were now upon the departure: tomorrow, by that time the sun be hot ; when it smites with the greatest heat, as at noon: this morrow seems not to be the next from their return home, or going from Saul, but the morrow after they were got home, and should deliver the message to those that sent them, ( 1 Samuel 11:10) and so Josephus says, it was on the third day the assistance was promised them: ye shall have help ; Saul with his army by that time would come and raise the siege: and the messengers came and showed it to the men of Jabesh; what Saul had promised, and what a numerous army he had raised, and had now upon the march for their relief, and tomorrow would be with them: and they were glad ; it was good news and glad tidings to them; it cheered their hearts, and gave them spirit.
Matthew Henry Commentary
Verses 1-11 - The first fruit of Saul's government was the rescue of Jabesh-gilea 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 tha 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.
