Numbers 11:25-27

Young's Literal Translation

²⁵ and Jehovah cometh down in the cloud, and speaketh unto him, and keepeth back of the Spirit which [is] on him, and putteth on the seventy men of the elders; and it cometh to pass at the resting of the Spirit on them, that they prophesy, and do not cease.

²⁶ And two of the men are left in the camp, the name of the one [is] Eldad, and the name of the second Medad, and the spirit resteth upon them, (and they are among those written, and have not gone out to the tent), and they prophesy in the camp;

²⁷ and the young man runneth, and declareth to Moses, and saith, `Eldad and Medad are prophesying in the camp.'
