Thematic Bible: Necessary to prophesying

And Jehovah came down in a cloud, and spoke to him, and took of the Spirit that was upon him, and put it upon the seventy men, the elders; and it came to pass, that when the Spirit rested on them, they prophesied, but they did not repeat it. And two men remained in the camp, the name of the one, Eldad, and the name of the other, Medad; and the Spirit rested upon them (and they were among them that were written, but they had not gone out to the tent); and they prophesied in the camp. And there ran a youth, and told Moses, and said, Eldad and Medad are prophesying in the camp.

Thus saith Jehovah unto you: Fear not, nor be dismayed by reason of this great multitude; for the battle is not yours, but God's.
