Passage
And thou shalt do that which is right and good in the sight of the LORD: that it may be well with thee, and that thou mayest go in and possess the good land which the LORD sware unto thy fathers,
And thou shalt do that which is right and good in the sight of the LORD: that it may be well with thee, and that thou mayest go in and possess the good land which the LORD sware unto thy fathers,
Deuteronomy 6:16 Ye shall not tempt the LORD your God, as ye tempted him in Massah.
Deuteronomy 6:17 Ye shall diligently keep the commandments of the LORD your God, and his testimonies, and his statutes, which he hath commanded thee.
Deuteronomy 6:18 And thou shalt do that which is right and good in the sight of the LORD: that it may be well with thee, and that thou mayest go in and possess the good land which the LORD sware unto thy fathers,
Deuteronomy 6:19 To cast out all thine enemies from before thee, as the LORD hath spoken.
Deuteronomy 6:20 And when thy son asketh thee in time to come, saying, What mean the testimonies, and the statutes, and the judgments, which the LORD our God hath commanded you?
The verse centers on "thou", "shalt", "right", "good", "sight", "lord", "well", and "thee". It is saying that the verse draws attention to "thou" and "shalt", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 17's "Ye shall diligently keep the commandments of..." into verse 19's "To cast out all thine enemies from...", so "thou" and "shalt" 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 "shalt" with trust shaped by these words, not by a vague optimism outside the passage.
