(13) Thou shalt be perfect with the Lord thy God.--Rashi's note on this is worth preserving: "Thou shalt walk with Him in sincerity, and wait for Him. And thou shalt not pry into the future. But whatsoever cometh upon thee, take it with simplicity, and then thou shalt be with Him, and be His portion."

Verse 13. - Thou shalt be perfect with the Lord thy God. The word translated "per-feet" properly means entire, whole, answering to the Latin integer; it is used only in a moral sense, and is best rendered by "upright;" the Israelites were to be upright and sincere with, i.e. in relation with, Jehovah their God.

18:9-14 Was it possible that a people so blessed with Divine institutions, should ever be in any danger of making those their teachers whom God had made their captives? They were in danger; therefore, after many like cautions, they are charged not to do after the abominations of the nations of Canaan. All reckoning of lucky or unlucky days, all charms for diseases, all amulets or spells to prevent evil, fortune-telling, &c. are here forbidden. These are so wicked as to be a chief cause of the rooting out of the Canaanites. It is amazing to think that there should be any pretenders of this kind in such a land, and day of light, as we live in. They are mere impostors who blind and cheat their followers.Thou shalt be perfect with the Lord thy God. Sincerely serve and worship him, faithfully adhere to his word, laws, statutes, and ordinances, and walk uprightly before him.
