Passage
All the commandment which I command thee this day shall ye observe to do, that ye may live, and multiply, and go in and possess the land which Jehovah sware unto your fathers.
All the commandment which I command thee this day shall ye observe to do, that ye may live, and multiply, and go in and possess the land which Jehovah sware unto your fathers.
Deuteronomy 8:1 All the commandment which I command thee this day shall ye observe to do, that ye may live, and multiply, and go in and possess the land which Jehovah sware unto your fathers.
Deuteronomy 8:2 And thou shalt remember all the way which Jehovah thy God hath led thee these forty years in the wilderness, that he might humble thee, to prove thee, to know what was in thy heart, whether thou wouldest keep his commandments, or not.
Deuteronomy 8:3 And he humbled thee, and suffered thee to hunger, and fed thee with manna, which thou knewest not, neither did thy fathers know; that he might make thee know that man doth not live by bread only, but by everything that proceedeth out of the mouth of Jehovah doth man live.
The verse centers on "commandment", "thee", "shall", "observe", "live", "multiply", and "possess". It is saying that the verse draws attention to "commandment" and "thee", so its meaning should be read from those terms before moving to application.
The next verse adds "And thou shalt remember all the way...", so "commandment" and "thee" should be read forward into that movement. In Deuteronomy context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "commandment" and "thee" with trust shaped by these words, not by a vague optimism outside the passage.
