Numbers 11:26-30 (New King James Version)

²⁶ 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. ²⁷ And a young man ran and told Moses, and said, “Eldad and Medad are prophesying in the camp.”
²⁸ So Joshua the son of Nun, Moses’ assistant, one of his choice men, answered and said, “Moses my lord, forbid them!”
²⁹ Then Moses said to him, “Are you zealous for my sake? Oh, that all the LORD’s people were prophets and that the LORD would put His Spirit upon them!” ³⁰ And Moses returned to the camp, he and the elders of Israel.
