When thou hast eaten and art full, then thou shalt bless the LORD thy God for the good land which he hath given thee.
Deuteronomy 8:8 A land of wheat, and barley, and vines, and fig trees, and pomegranates; a land of oil olive, and honey;
Deuteronomy 8:9 A land wherein thou shalt eat bread without scarceness, thou shalt not lack any thing in it; a land whose stones are iron, and out of whose hills thou mayest dig brass.
Deuteronomy 8:10 When thou hast eaten and art full, then thou shalt bless the LORD thy God for the good land which he hath given thee.
Deuteronomy 8:11 Beware that thou forget not the LORD thy God, in not keeping his commandments, and his judgments, and his statutes, which I command thee this day:
Deuteronomy 8:12 Lest when thou hast eaten and art full, and hast built goodly houses, and dwelt therein;
The verse centers on "thou", "hast", "eaten", "full", "shalt", "bless", and "lord". It is saying that the verse draws attention to "thou" and "hast", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 9's "A land wherein thou shalt eat bread..." into verse 11's "Beware that thou forget not the LORD...", so "thou" and "hast" 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 "thou" and "hast" with trust shaped by these words, not by a vague optimism outside the passage.
