Numbers 11:25-27

25And 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].

26And 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.

27And there ran a youth, and told Moses, and said, Eldad and Medad are prophesying in the camp.
