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 and what he did to Dathan and Abiram, the descendants of Eliab the Reubenite, when the ground opened up its mouth and swallowed them, their families, their tents, and every living thing they possessed in the presence of all Israel.

7 Your own eyes witnessed each of these powerful acts the LORD performed.

8 So keep every part of the commandment that I am giving you today so that you stay strong to enter and take possession of the land that you are crossing over to possess,

9 and so that you might prolong your life on the fertile land that the LORD swore to your ancestors to give to them and their descendants—a land full of milk and honey.

10 The land you are about to enter and possess is definitely not like the land of Egypt, where you came from, where you sowed your seed and irrigated it by hand like a vegetable garden.
