Numbers 11:25-29 (KJV)
25 And the Lord came down in a cloud, and spake unto him, and took of the spirit that was upon him, and gave it unto the seventy elders: and it came to pass, that, when the spirit rested upon them, they prophesied, and did not cease.
26 But there remained two of the men in the camp, 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, but went not out unto the tabernacle: and they prophesied in the camp.
27 And there ran a young man, and told Moses, and said, Eldad and Medad do prophesy in the camp.
28 And Joshua the son of Nun, the servant of Moses, one of his young men, answered and said, My lord Moses, forbid them.
29 And Moses said unto him, Enviest thou for my sake? would God that all the Lord’S people were prophets, and that the Lord would put his spirit upon them!
