Passage
Ye shall keepe all the commandements which I command thee this day, for to doe them: that ye may liue, and be multiplied, and goe in, and possesse the land which the Lord sware vnto your fathers.
Ye shall keepe all the commandements which I command thee this day, for to doe them: that ye may liue, and be multiplied, and goe in, and possesse the land which the Lord sware vnto your fathers.
Deuteronomy 8:1 Ye shall keepe all the commandements which I command thee this day, for to doe them: that ye may liue, and be multiplied, and goe in, and possesse the land which the Lord sware vnto your fathers.
Deuteronomy 8:2 And thou shalt remember all ye way which the Lord thy God led thee this fourtie yeere in the wildernesse, for to humble thee and to proue thee, to knowe what was in thine heart, whether thou wouldest keepe his commandements or no.
Deuteronomy 8:3 Therefore he humbled thee, and made thee hungry, and fed thee with MAN, which thou knewest not, neither did thy fathers know it, that he might teache thee that man liueth not by bread onely, but by euery worde that proceedeth out of the mouth of the Lord, doth a man liue.
The verse centers on "shall", "keepe", "commandements", "thee", "liue", "multiplied", and "possesse". It is saying that the verse draws attention to "shall" and "keepe", so its meaning should be read from those terms before moving to application.
The next verse adds "And thou shalt remember all ye way...", so "shall" and "keepe" 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 "shall" and "keepe" with trust shaped by these words, not by a vague optimism outside the passage.
