Passage
and thou shalt impress them on thy sons, and shalt talk of them when thou sittest in thy house, and when thou goest on the way, and when thou liest down, and when thou risest up.
and thou shalt impress them on thy sons, and shalt talk of them when thou sittest in thy house, and when thou goest on the way, and when thou liest down, and when thou risest up.
Deuteronomy 6:5 and thou shalt love Jehovah thy God with all thy heart, and with all thy soul, and with all thy strength.
Deuteronomy 6:6 And these words, which I command thee this day, shall be in thy heart;
Deuteronomy 6:7 and thou shalt impress them on thy sons, and shalt talk of them when thou sittest in thy house, and when thou goest on the way, and when thou liest down, and when thou risest up.
Deuteronomy 6:8 And thou shalt bind them for a sign on thy hand, and they shall be for frontlets between thine eyes.
Deuteronomy 6:9 And thou shalt write them upon the posts of thy house, and upon thy gates.
The verse centers on "thou", "shalt", "impress", "sons", "talk", and "sittest". 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 6's "And these words which I command thee..." into verse 8's "And thou shalt bind them for a...", 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.
