What did Jethro tell Moses to teach the people in Exodus 18:20?
Jethro instructed Moses to teach the people ordinances and laws, to show them the way they must walk, and to show them the work they must do. This counsel appears in Exodus 18:20, though the chapter presents Jethro speaking without the Lord's direction.
Les explains that Jethro, Moses' father-in-law, advised Moses to teach Israel ordinances and laws, show them the way to walk, and show them the work to do. Les points out that Jethro also told Moses to provide able men who fear God, men of truth who hate covetousness, as rulers over thousands, hundreds, fifties, and rulers. Les emphasizes that the Lord is not speaking in this chapter; it is a man speaking in the energy of the flesh, though the advice sounds logical. Moses hearkened to his father-in-law and did all he said.
And thou shalt teach them ordinances and laws, and shalt shew them the way wherein they must walk, and the work that they must do.
