Numbers 11:24-25 NIV

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 some of the power of the Spirit that was on him and put it on the seventy elders. When the Spirit rested on them, they prophesied—but did not do so again.
