Numbers 11:24-26

24So Moses went out and spoke to the people the words of the Lord, and he gathered seventy men from among the elders of the people and stationed them around the Tent (tabernacle).

25Then the Lord came down in the cloud and spoke to him; and He took some of the Spirit who was upon Moses and put Him upon the seventy elders. When the Spirit rested upon them, they prophesied [praising God and declaring His will], but they did not do it again.

26But two men had remained in the camp; one named Eldad and the other named Medad. The Spirit rested upon them (now they were among those who had been registered, but had not gone out to the Tent), and they prophesied in the camp.
