Passage
Thus sayth the Lord, If you can breake my couenant of the day, and my couenant of the night, that there should not be day, and night in their season,
Thus sayth the Lord, If you can breake my couenant of the day, and my couenant of the night, that there should not be day, and night in their season,
Jeremiah 33:18 Neither shall the Priests and Leuites want a man before me to offer burnt offerings, and to offer meat offerings, and to doe sacrifice continually.
Jeremiah 33:19 And the worde of the Lord came vnto Ieremiah, saying,
Jeremiah 33:20 Thus sayth the Lord, If you can breake my couenant of the day, and my couenant of the night, that there should not be day, and night in their season,
Jeremiah 33:21 Then may my couenant be broken with Dauid my seruant, that he should not haue a sonne to reigne vpon his throne, and with the Leuites, and Priests my ministers.
Jeremiah 33:22 As the army of heauen can not be nombred, neither the sand of the sea measured: so wil I multiplie the seede of Dauid my seruant, and the Leuites, that minister vnto me.
The verse centers on "thus", "sayth", "lord", "breake", "couenant", "night", and "should". It is saying that the verse draws attention to "thus" and "sayth", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 19's "And the worde of the Lord came..." into verse 21's "Then may my couenant be broken with...", so "thus" and "sayth" belong inside that flow. In Jeremiah context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "thus" and "sayth" with trust shaped by these words, not by a vague optimism outside the passage.
