Yirmeyah 17:1-2

Orthodox Jewish Bible

17 The chattat Yehudah is written with an et barzel (iron pen), and with the tzipporen shamir (point of a diamond); it is engraved upon the luach (tablet) of their lev, and upon the karenot (horns) of your mizbechot (altars);

² Whilst their banim remember their mizbechot and their asherim by the leafy trees upon the high hills.
