Deuteronomy 13:18 Meaning and Commentary

Deuteronomy 13:18

When thou shalt hearken to the voice of the Lord thy God
Not only in this case, but in all others:

to keep all his commandments which I command thee this day:
the repetition of which he made unto them, and enjoined the observance of them in the name of the Lord:

to do that which is right in the eyes of the Lord thy God;
which they would do, if they kept the commandments of the Lord, which are holy, just, and good, and must be right in his sight because commanded by him.

Deuteronomy 13:18 In-Context

16 And all its spoils thou shalt gather into its public ways, and thou shalt burn the city with fire, and all its spoils publicly before the Lord thy God; and it shall be uninhabited for ever, it shall not be built again.
17 And there shall nothing of the cursed thing cleave to thy hand, that the Lord may turn from his fierce anger, and shew thee mercy, and pity thee, and multiply thee, as he sware to thy fathers;
18 if thou wilt hear the voice of the Lord thy God, to keep his commandments, all that I charge thee this day, to do that which is good and pleasing before the Lord thy God.
