Passage
`And thou dost turn back, and hast hearkened to the voice of Jehovah, and hast done all His commands which I am commanding thee to-day;
`And thou dost turn back, and hast hearkened to the voice of Jehovah, and hast done all His commands which I am commanding thee to-day;
Deuteronomy 30:6 `And Jehovah thy God hath circumcised thy heart, and the heart of thy seed, to love Jehovah thy God with all thy heart, and with all thy soul, for the sake of thy life;
Deuteronomy 30:7 and Jehovah thy God hath put all this oath on thine enemies, and on those hating thee, who have pursued thee.
Deuteronomy 30:8 `And thou dost turn back, and hast hearkened to the voice of Jehovah, and hast done all His commands which I am commanding thee to-day;
Deuteronomy 30:9 and Jehovah thy God hath made thee abundant in every work of thy hand, in the fruit of thy body, and in the fruit of thy cattle, and in the fruit of thy ground, for good; for Jehovah turneth back to rejoice over thee for good, as He rejoiced over thy fathers,
Deuteronomy 30:10 for thou dost hearken to the voice of Jehovah thy God, to keep His commands, and His statutes, which are written in the book of this law, for thou turnest back unto Jehovah thy God, with all thy heart, and with all thy soul.
The verse centers on "thou", "dost", "turn", "back", "hast", "hearkened", "voice", and "jehovah". It is saying that the verse draws attention to "thou" and "dost", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 7's "and Jehovah thy God hath put all..." into verse 9's "and Jehovah thy God hath made thee...", so "thou" and "dost" 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 "dost" with trust shaped by these words, not by a vague optimism outside the passage.
