Numbers 11:16-17

16So the Lord said to Moses, ‘Choose 70 leaders of the Israelites and bring them to the Tent of Meeting. You must know that they are leaders and officers that the people respect. Bring them to stand there with you.

17Then I will come down and I will speak with you there. I will take some of the authority of my Spirit that I gave to you. I will share it with them. Then they will help you to lead the people. So you will not be the only man who is doing that job.
