Passage
The sin of Judah is written with a style of iron, with the point of a diamond, engraven upon the tablet of their heart, and upon the horns of your altars;
The sin of Judah is written with a style of iron, with the point of a diamond, engraven upon the tablet of their heart, and upon the horns of your altars;
Jeremiah 17:1 The sin of Judah is written with a style of iron, with the point of a diamond, engraven upon the tablet of their heart, and upon the horns of your altars;
Jeremiah 17:2 whilst their children remember their altars and their Asherahs, by the green trees, upon the high hills.
Jeremiah 17:3 My mountain in the field, thy substance, all thy treasures will I give for a spoil, thy high places, because of sin throughout thy borders.
The verse centers on "judah", "written", "style", "iron", "point", "diamond", "engraven", and "upon". It is saying that the verse draws attention to "judah" and "written", so its meaning should be read from those terms before moving to application.
The next verse adds "whilst their children remember their altars and...", so "judah" and "written" should be read forward into that movement. In Jeremiah context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "judah" and "written" with trust shaped by these words, not by a vague optimism outside the passage.
