Passage
“So it will be, when all of these things have come upon you, the blessing and the curse which I have set before you, and you cause these things to return to your heart in all the nations where Yahweh your God has banished you,
“So it will be, when all of these things have come upon you, the blessing and the curse which I have set before you, and you cause these things to return to your heart in all the nations where Yahweh your God has banished you,
Deuteronomy 30:1 “So it will be, when all of these things have come upon you, the blessing and the curse which I have set before you, and you cause these things to return to your heart in all the nations where Yahweh your God has banished you,
Deuteronomy 30:2 and you return to Yahweh your God and listen to His voice with all your heart and soul according to all that I am commanding you today, you and your sons,
Deuteronomy 30:3 then Yahweh your God will return you from captivity and return His compassion on you, and He will gather you again from all the peoples where Yahweh your God has scattered you.
The verse centers on "things", "come", "upon", "blessing", "curse", "before", and "cause". It is saying that the verse draws attention to "things" and "come", so its meaning should be read from those terms before moving to application.
The next verse adds "and you return to Yahweh your God...", so "things" and "come" should be read forward into that movement. In Deuteronomy context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "things" and "come" with trust shaped by these words, not by a vague optimism outside the passage.
