Job 19:24

The 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;

And the stones shall be with the names of the children of Israel, twelve, according to their names, like the engravings of a signet; every one with his name shall they be according to the twelve tribes.

And thou shalt write upon the stones all the words of this law very plainly.

And the tables were the work of God, and the writing was the writing of God, graven upon the tables.
