Numbers 11:25-26

25Then the Lord came down in the cloud and spoke with him, and he took some of the power of the Spirit that was on him and put it on the seventy elders. When the Spirit rested on them, they prophesied—but did not do so again. 26However, two men, whose names were Eldad and Medad, had remained in the camp. They were listed among the elders, but did not go out to the tent. Yet the Spirit also rested on them, and they prophesied in the camp.
