So Moses went out and told the people the words of the Lord. He then gathered seventy men of the elders of the people and had them stand around the tabernacle.

And the Lord came down in the cloud and spoke to them, and he took some of the Spirit that was on Moses and put it on the seventy elders. When the Spirit rested on them, they prophesied, but did not do so again.

They traveled from Marah and came to Elim; in Elim there are twelve fountains of water and seventy palm trees, so they camped there.
