Numbers 11:16-17,24-29 (Pentecost Vespers, 1st Reading)
And the LORD said to Moses, “Gather for me seventy men of the elders of Israel, whom you know to be the elders of the people and officers over them; and bring them to the tent of meeting, and let them take their stand there with you. And I will come down and talk with you there; and I will take some of the spirit which is upon you and put it upon them; and they shall bear the burden of the people with you, that you may not bear it yourself alone.
So Moses went out and told the people the words of the LORD; and he gathered seventy men of the elders of the people, and placed them round about the tent. Then the LORD came down in the cloud and spoke to him, and took some of the spirit that was upon him and put it upon the seventy elders; and when the spirit rested upon them, they prophesied. But they did so no more. Now two men remained in the camp, one named Eldad, and the other named Medad, and the spirit rested upon them; they were among those registered, but they had not gone out to the tent, and so they prophesied in the camp. And a young man ran and told Moses, “Eldad and Medad are prophesying in the camp.” And Joshua the son of Nun, the minister of Moses, one of his chosen men, said, “My lord Moses, forbid them.” But Moses said to him, “Are you jealous for my sake? Would that all the LORD’s people were prophets, that the LORD would put his spirit upon them!”
