Numbers 11:24-26

24And Moses went out and told the people the words of Jehovah; and he gathered the seventy men of the elders of the people, and set them round about the tent.

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.
