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 Gather up everything those people owned, and put it in the middle of the city square. Then completely burn the city and everything they owned as a burnt offering to the Lord your God. That city should never be rebuilt; let it be ruined forever.

17 Don't keep for yourselves any of the things found in that city, so the Lord will not be angry anymore. He will give you mercy and feel sorry for you, and he will make your nation grow larger, as he promised to your ancestors.

18 You will have obeyed the Lord your God by keeping all his commands that I am giving to you today, and you will be doing what the Lord says is right.
