Numbers 11:24-26

ISV(i) 24 So Moses went out and told the people what the LORD had said. He gathered 70 men from the elders of the people and stationed them around the tent. 25 The LORD came down in a cloud, spoke to Moses, and made an apportionment from the spirit who rested on him to the 70 elders. When the spirit rested on them, they prophesied, but that was it.
26 Now two men had remained in camp. One was named Eldad and the other was named Medad. When the spirit rested on them, since they were among those who were listed but had not gone out to the tent, they stayed behind and prophesied in the camp.
