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, sons of Eliab son of Reuben, how in the midst of all Israel the earth opened its mouth and swallowed them up, along with their households, their tents, and every living being in their company;
7 for it is your own eyes that have seen every great deed that the Lord did.
8 Keep, then, this entire commandment that I am commanding you today, so that you may have strength to go in and occupy the land that you are crossing over to occupy,
9 and so that you may live long in the land that the Lord swore to your ancestors to give them and to their descendants, a land flowing with milk and honey.
10 For the land that you are about to enter to occupy is not like the land of Egypt, from which you have come, where you sow your seed and irrigate by foot like a vegetable garden.
