Numbers 11:24-25
24 So Moses went out and told the people what the Lord had said. He brought together seventy of their elders and had them stand around the Tent.
25 Then the Lord came down in the cloud and spoke with him, and he took of the Spirit that was on him and put the Spirit on the seventy elders. When the Spirit rested on them, they prophesied, but they did not do so again.
