Exodus 18:20

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.

Ver. 20. And thou shalt teach them ordinances.] This alone will be work enough for thee, if done as it ought to be.

And shalt show them the way wherein they must walk.] The Chaldee Paraphrast hath it thus, And shalt show them the prayer which they shall pray in their synagogues.
