Passage
Therefore thou shalt keep the commandments of the LORD thy God, to walk in his ways, and to fear him.
Therefore thou shalt keep the commandments of the LORD thy God, to walk in his ways, and to fear him.
Deuteronomy 8:4 Thy raiment waxed not old upon thee, neither did thy foot swell, these forty years.
Deuteronomy 8:5 Thou shalt also consider in thine heart, that, as a man chasteneth his son, so the LORD thy God chasteneth thee.
Deuteronomy 8:6 Therefore thou shalt keep the commandments of the LORD thy God, to walk in his ways, and to fear him.
Deuteronomy 8:7 For the LORD thy God bringeth thee into a good land, a land of brooks of water, of fountains and depths that spring out of valleys and hills;
Deuteronomy 8:8 A land of wheat, and barley, and vines, and fig trees, and pomegranates; a land of oil olive, and honey;
The verse centers on "therefore", "thou", "shalt", "keep", "commandments", "lord", "walk", and "ways". It is saying that the verse draws attention to "therefore" and "thou", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 5's "Thou shalt also consider in thine heart..." into verse 7's "For the LORD thy God bringeth thee...", so "therefore" 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 "therefore" and "thou" with trust shaped by these words, not by a vague optimism outside the passage.
