Passage
Every commandment which I command thee this day shall ye take heed to do, that ye may live, and multiply, and enter in and possess the land which Jehovah swore unto your fathers.
Every commandment which I command thee this day shall ye take heed to do, that ye may live, and multiply, and enter in and possess the land which Jehovah swore unto your fathers.
Deuteronomy 8:1 Every commandment which I command thee this day shall ye take heed to do, that ye may live, and multiply, and enter in and possess the land which Jehovah swore unto your fathers.
Deuteronomy 8:2 And thou shalt remember all the way which Jehovah thy God led thee these forty years in the wilderness, to humble thee, and 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 the manna, which thou hadst not known, and which thy fathers knew not; that he might make thee know that man doth not live by bread alone, but by everything that goeth out of the mouth of Jehovah doth man live.
The verse centers on "commandment", "thee", "shall", "take", "heed", "live", and "multiply". 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.
