Bible Verses About Precious Stones: Art of engraving upon, early known to the Jews

You shall take two onyx stones, and engrave on them the names of the children of Israel:

With the work of an engraver in stone, like the engravings of a signet, you shall engrave the two stones, according to the names of the children of Israel: you shall make them to be enclosed in settings of gold.

The stones shall be according to the names of the children of Israel, twelve, according to their names; like the engravings of a signet, everyone according to his name, they shall be for the twelve tribes.
