Will come upon thee, Heb. will leap or rush on thee, to wit, for a season. So it may be opposed to the Spirit's resting upon a man, as Numbers 11:25 Isaiah 11:2. Shalt be turned into another man, i.e. thou shalt be suddenly endowed and acted with another spirit, filled with skill of Divine things, with courage, and wisdom, and magnanimity, and other qualifications befitting thy dignity.
