Numbers 11
24 Ref And Moses went out and gave the people the words of the Lord: and he took seventy of the responsible men of the people, placing them round the Tent.
25 Ref Then the Lord came down in the cloud and had talk with him, and put on the seventy men some of the spirit which was on him: now when the spirit came to rest on them, they were like prophets, but only at that time.
26 Ref But two men were still in the tent-circle one of them named Eldad and the other Medad: and the spirit came to rest on them; they were among those who had been sent for, but they had not gone out to the Tent: and the prophet's power came on them in the tent-circle.
