Numbers 11:16-17

16The Lord said to Moses, “Gather to me seventy men of the elders of Israel, whom you know are elders of the people and officials over them, and bring them to the tent of meeting; let them take their position there with you.

17Then I will come down and speak with you there, and I will take part of the spirit that is on you, and will put it on them, and they will bear some of the burden of the people with you, so that you do not bear it all by yourself.
