Passage
And thou shalt do what is right and good in the sight of Jehovah, that it may be well with thee, and that thou mayest enter in and possess the good land which Jehovah swore unto thy fathers,
And thou shalt do what is right and good in the sight of Jehovah, that it may be well with thee, and that thou mayest enter in and possess the good land which Jehovah swore unto thy fathers,
Deuteronomy 6:16 Ye shall not tempt Jehovah your God, as ye tempted him in Massah.
Deuteronomy 6:17 Ye shall diligently keep the commandments of Jehovah your God, and his testimonies, and his statutes, which he hath commanded thee.
Deuteronomy 6:18 And thou shalt do what is right and good in the sight of Jehovah, that it may be well with thee, and that thou mayest enter in and possess the good land which Jehovah swore unto thy fathers,
Deuteronomy 6:19 thrusting out all thine enemies from before thee, as Jehovah hath spoken.
Deuteronomy 6:20 When thy son shall ask thee in time to come, saying, What are the testimonies, and the statutes, and the ordinances, which Jehovah our God hath commanded you?
The verse centers on "thou", "shalt", "right", "good", "sight", "jehovah", "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 "thrusting out all thine enemies from before...", 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.
