1 Samuel 10:6

The spirit of Jehovah will come upon thee. The Hebrew means, will come mightily upon thee, will come upon thee so as to overpower thee. And thou shalt prophesy. Shalt act as a prophet (see above). Albeit untrained, thou shalt be carried away by religious fervour, and join in their singing and psalmody. And be turned into another man. New thoughts, new emotions shall take possession of thee, and in addition to the bodily strength for which hitherto thou hast been famous, thou shalt be filled with mental power, making thee eager for action and capable of taking the lead among all men, and in all emergencies. We have an instance of this enlarged capacity in the vigour with which Saul acted against the Ammonites.
