Numbers 11:25-26

Then the LORD came down in the cloud, and spoke to him, and took of the Spirit that was upon him, and placed the same upon the seventy elders; and it happened, when the Spirit rested upon them, that they prophesied, although they never did so again. But two men had remained in the camp: the name of one was Eldad, and the name of the other Medad. And the Spirit rested upon them. Now they were among those listed, but who had not gone out to the tabernacle; yet they prophesied in the camp.
