Jeremiah 7:18 The children gather wood, and the fathers kindle the fire, and the women knead the dough, to make cakes to the queen of heaven, and to pour out drink-offerings unto other gods, that they may provoke me to anger.

Jeremiah 7:20 Therefore thus saith the Lord Jehovah: Behold, mine anger and my wrath shall be poured out upon this place, upon man, and upon beast, and upon the trees of the field, and upon the fruit of the ground; and it shall burn, and shall not be quenched.
Jeremiah 7:21 Thus saith Jehovah of hosts, the God of Israel: Add your burnt-offerings unto your sacrifices, and eat ye flesh.
Jeremiah 7:22 For I spake not unto your fathers, nor commanded them in the day that I brought them out of the land of Egypt, concerning burnt-offerings or sacrifices:
The verse centers on "therefore", "thus", "saith", "lord", "jehovah", "behold", "mine", and "anger". It is saying that the verse draws attention to "therefore" and "thus", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 19's "Do they provoke me to anger saith..." into verse 21's "Thus saith Jehovah of hosts the God...", so "therefore" and "thus" 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 "therefore" and "thus" with trust shaped by these words, not by a vague optimism outside the passage.
