16 If thou wilt hearken to the commands of the Lord thy God, which I command thee this day, to love the Lord thy God, to walk in all his ways, and to keep his ordinances, and his judgments; then ye shall live, and shall be many in number, and the Lord thy God shall bless thee in all the land into which thou goest to inherit it.

Deuteronomy 30:16 Meaning and Commentary

Deuteronomy 30:16

In that I command thee this day to love the Lord thy God
Which is the sum and substance of the first table of the law, and includes the whole worship of God, the contrary to which are idolatry, superstition, and will worship, from which Moses had been dissuading and deterring them:

to walk in his ways;
which he has prescribed, as his will to walk in, and his law directs to:

and to keep his commandments, and his statutes, and his judgments;
his laws, moral, ceremonial, and judicial, Moses had been repeating and reciting:

that thou mayest live and multiply;
live in the land of Canaan, and have a numerous offspring and posterity to succeed and continue in it, which is confirmed by what follows:

and the Lord thy God shall bless thee in the land whither thou goest
to possess it;
with health and happiness, with an affluence of all good things, in the land of Canaan they were just entering into to take possession of.

Deuteronomy 30:16 In-Context

14 The word is very near thee, in thy mouth, and in thine heart, and in thine hands to do it.
15 Behold, I have set before thee this day life and death, good and evil.
16 If thou wilt hearken to the commands of the Lord thy God, which I command thee this day, to love the Lord thy God, to walk in all his ways, and to keep his ordinances, and his judgments; then ye shall live, and shall be many in number, and the Lord thy God shall bless thee in all the land into which thou goest to inherit it.
17 But if thy heart change, and thou wilt not hearken, and thou shalt go astray and worship other gods, and serve them,
18 I declare to you this day, that ye shall utterly perish, and ye shall by no means live long upon the land, into which ye go over Jordan to inherit it.
