Numbers 11:26

But there remained two of the men in the camp, of the elders who should have been at the Tabernacle; the name of the one was Eldad and the name of the other Medad; and the Spirit rested upon them; and they were of them that were written, their names were included in the list made by Moses, but went not out unto the Tabernacle; and they prophesied in the camp.
