Passage
And it shall be, when Jehovah thy God shall bring thee into the land which he sware unto thy fathers, to Abraham, to Isaac, and to Jacob, to give thee, great and goodly cities, which thou buildest not,
And it shall be, when Jehovah thy God shall bring thee into the land which he sware unto thy fathers, to Abraham, to Isaac, and to Jacob, to give thee, great and goodly cities, which thou buildest not,
Deuteronomy 6:8 And thou shalt bind them for a sign upon thy hand, and they shall be for frontlets between thine eyes.
Deuteronomy 6:9 And thou shalt write them upon the door-posts of thy house, and upon thy gates.
Deuteronomy 6:10 And it shall be, when Jehovah thy God shall bring thee into the land which he sware unto thy fathers, to Abraham, to Isaac, and to Jacob, to give thee, great and goodly cities, which thou buildest not,
Deuteronomy 6:11 and houses full of all good things, which thou filledst not, and cisterns hewn out, which thou hewedst not, vineyards and olive-trees, which thou plantedst not, and thou shalt eat and be full;
Deuteronomy 6:12 then beware lest thou forget Jehovah, who brought thee forth out of the land of Egypt, out of the house of bondage.
The verse centers on "shall", "jehovah", "bring", "thee", "land", "sware", and "fathers". It is saying that the verse draws attention to "shall" and "jehovah", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 9's "And thou shalt write them upon the..." into verse 11's "and houses full of all good things...", so "shall" and "jehovah" belong inside that flow. 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 "jehovah" with trust shaped by these words, not by a vague optimism outside the passage.
