Passage
And I will cleanse them from all their iniquity, whereby they have sinned against me; and I will pardon all their iniquities, whereby they have sinned against me, and whereby they have transgressed against me.
And I will cleanse them from all their iniquity, whereby they have sinned against me; and I will pardon all their iniquities, whereby they have sinned against me, and whereby they have transgressed against me.
Jeremiah 33:6 Behold, I will bring it health and cure, and I will cure them; and I will reveal unto them abundance of peace and truth.
Jeremiah 33:7 And I will cause the captivity of Judah and the captivity of Israel to return, and will build them, as at the first.
Jeremiah 33:8 And I will cleanse them from all their iniquity, whereby they have sinned against me; and I will pardon all their iniquities, whereby they have sinned against me, and whereby they have transgressed against me.
Jeremiah 33:9 And [this city] shall be to me for a name of joy, for a praise and for a glory, before all the nations of the earth, which shall hear all the good that I do unto them, and shall fear and tremble for all the good and for all the peace that I procure unto it.
Jeremiah 33:10 Thus saith Jehovah: Yet again there shall be heard in this place, whereof ye say, It is waste, without man and without beast, even in the cities of Judah, and in the streets of Jerusalem, that are desolate, without man and without inhabitant and without beast,
The verse centers on "iniquities", "cleanse", "iniquity", "whereby", "sinned", "against", and "pardon". It is saying that the verse draws attention to "iniquities" and "cleanse", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 7's "And I will cause the captivity of..." into verse 9's "And this city shall be to me...", so "iniquities" and "cleanse" 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 "iniquities" and "cleanse" with trust shaped by these words, not by a vague optimism outside the passage.
