Deuteronomy 30:4 If [any of] thine outcasts be in the uttermost parts of heaven, from thence will Jehovah thy God gather thee, and from thence will he fetch thee:
The verse centers on "shalt", "return", "jehovah", "obey", "voice", "command", and "thee". It is saying that the verse draws attention to "shalt" and "return", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 1's "And it shall come to pass when..." into verse 3's "that then Jehovah thy God will turn...", so "shalt" and "return" 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 "shalt" and "return" with trust shaped by these words, not by a vague optimism outside the passage.
