Context Reading
1The sin of Judah is written with a pen of iron, and with the point of a diamond: it is graven upon the table of their heart, and upon the horns of your altars; 2Whilst their children remember their altars and their groves by the green trees upon the high hills. 3O my mountain in the field, I will give thy substance and all thy treasures to the spoil, and thy high places for sin, throughout all thy borders.
