And thou shalt say unto them, This is the nation which hath not hearkened unto the voice of Jehovah their God, nor received correction; fidelity is perished, and is cut off from their mouth.
And thou shalt say unto them, This is the nation which hath not hearkened unto the voice of Jehovah their God, nor received correction; fidelity is perished, and is cut off from their mouth.
Jeremiah 7:26 but they have not hearkened unto me, nor inclined their ear; and they have hardened their neck: they have done worse than their fathers.
Jeremiah 7:27 And thou shalt speak all these words unto them, but they will not hearken unto thee; and thou shalt call unto them, but they will not answer thee.

Jeremiah 7:29 Cut off thy hair, and cast it away, and take up a lamentation on the heights; for Jehovah hath rejected and forsaken the generation of his wrath.
Jeremiah 7:30 For the children of Judah have done evil in my sight, saith Jehovah; they have set their abominations in the house which is called by my name, to defile it.
The verse centers on "thou", "shalt", "nation", "hath", "hearkened", "voice", "jehovah", and "received". It is saying that the verse draws attention to "thou" and "shalt", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 27's "And thou shalt speak all these words..." into verse 29's "Cut off thy hair and cast it...", so "thou" and "shalt" 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 "thou" and "shalt" with trust shaped by these words, not by a vague optimism outside the passage.
