Will come upon thee - The word rendered “come,” means to “come” or “pass upon,” as fire does when it breaks out and spreads Amos 5:6; hence, it is frequently used of the Spirit of God passing upon anyone. (See Judges 14:19; Judges 15:14; below 1 Samuel 10:10; 1 Samuel 11:6; 1 Samuel 16:13.)
Shalt be turned into another man - This is a remarkable expression, and occurs nowhere else. It describes the change in point of mental power and energy which would result from the influx of the Spirit of the Lord 1 Samuel 10:9. In the case of Samson it was a supernatural bodily strength; in the case of Saul a capacity for ruling and leading the people of which before he was destitute, and which the Spirit worked in him. (Compare Acts 1:8; Isaiah 11:2-4.)
