1 Samuel 11:6

And the Spirit of God came upon Saul. — Nothing, perhaps, could have moved Saul so deeply as this news respecting the distress of Jabesh-gilead; he was affected not merely by the disgrace to Israel over which the Eternal had so lately directed him to be anointed king, but by the sore peril which menaced the ancient friend and ally of his tribe. On Saul’s heart, thus prepared for action, the Holy Spirit fell, and endued him with extraordinary wisdom, valour, and power for the great and difficult work which lay before him.

We read of the Spirit of the Lord coming upon men like Othniel (Judges 3:10) and the other great Israelitic judges, who were raised up to be in their day the deliverers of the people; and the immediate result of the Spirit of the Lord coming upon them was to impart new and unusual power to their spirit, power which enabled them successfully to surmount every danger and difficulty which barred the progress of the great work they were specially called upon to do.
