Deuteronomy 11:8 Meaning and Commentary

Deuteronomy 11:8

Therefore shall you keep all the commandments which I command
you this day
For the reasons before suggested, as well as for what follow:

that ye may be strong;
healthful in body, and courageous in mind, for sin tends to weaken both; whereas observance of the commands of God contributes to the health and strength of the body, and the rigour of the mind; both which were necessary to the present expedition they were going upon:

and go in and possess the land whither ye go to possess it;
the land of Canaan, they were marching towards in order to possess it; and nothing would more inspire them with courage, and cause them to enter it manfully without fear of their enemies, than obedience to the commands of God; whose presence being promised them on that account, they might expect it, and so had nothing to fear from the inhabitants of the land.

Deuteronomy 11:8 In-Context

6 You also saw what he did to Dathan and Abiram, the sons of Eliab, from the tribe of Reuben. In the middle of all the Israelites the ground opened up and swallowed them, their families, their tents, and every living creature with them.

7 You saw with your own eyes all these spectacular things that the LORD did.

8 Obey all the commands I'm giving you today. Then you will have the strength to enter and take possession of the land once you've crossed [the Jordan River].

9 Then you will also live for a long time in the land the LORD swore to give your ancestors and their descendants--a land flowing with milk and honey.

10 The land you're about to enter and take possession of isn't like the land you left in Egypt. There you used to plant your seed, and you had to water it like a vegetable garden.
