lest, when thou hast eaten and art full, and hast built goodly houses, and dwelt therein;
lest, when thou hast eaten and art full, and hast built goodly houses, and dwelt therein;
Deuteronomy 8:10 And thou shalt eat and be full, and thou shalt bless Jehovah thy God for the good land which he hath given thee.
Deuteronomy 8:11 Beware lest thou forget Jehovah thy God, in not keeping his commandments, and his ordinances, and his statutes, which I command thee this day:

Deuteronomy 8:14 then thy heart be lifted up, and thou forget Jehovah thy God, who brought thee forth out of the land of Egypt, out of the house of bondage;
The verse centers on "lest", "thou", "hast", "eaten", "full", "built", and "goodly". It is saying that the verse draws attention to "lest" and "thou", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 11's "Beware lest thou forget Jehovah thy God..." into verse 13's "and when thy herds and thy flocks...", so "lest" and "thou" 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 "lest" and "thou" with trust shaped by these words, not by a vague optimism outside the passage.
