While Moses was probably displeased at what the people were doing, he was also displeased with God and what He was doing. Moses did not understand what was going on, either. So he makes a complaint.
Now remember that he already had the other ones appointed.
I want you to notice that the title shifted here—from "judges" to "elders." Does that indicate anything to you? The pattern is already set in what happened following the experience of Moses with his father-in-law, Jethro. The pattern is set, but here assistance is given to Moses of a spiritual—rather than a secular—nature. The problem here was bad attitudes. Moses was simply unable to minister spiritually to all of these people. And so God took of His Holy Spirit (that He had given to Moses); and He distributed to the seventy the same Spirit. So we have a group of men; and it is quite possible that many (or, some) of these seventy were the same men as in the Exodus 18 incident.
