Passage
For thus says Yahweh, ‘David shall not have a man cut off from sitting on the throne of the house of Israel;
For thus says Yahweh, ‘David shall not have a man cut off from sitting on the throne of the house of Israel;
Jeremiah 33:15 In those days and at that time I will cause a righteous Branch of David to branch forth; and He shall do justice and righteousness on the earth.
Jeremiah 33:16 In those days Judah will be saved, and Jerusalem will dwell in security; and this is the name by which she will be called: Yahweh is our righteousness.’
Jeremiah 33:17 For thus says Yahweh, ‘David shall not have a man cut off from sitting on the throne of the house of Israel;
Jeremiah 33:18 and the Levitical priests shall not have a man cut off from before Me who is to offer burnt offerings, to offer up grain offerings in smoke, and to perform sacrifices continually.’”

The verse centers on "thus", "says", "yahweh", "david", "shall", "sitting", "throne", and "house". It is saying that the verse draws attention to "thus" and "says", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 16's "In those days Judah will be saved..." into verse 18's "and the Levitical priests shall not have...", so "thus" and "says" 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 "says" with trust shaped by these words, not by a vague optimism outside the passage.
