Exodus 39:16

¹⁴  And the stones were according to the names of the children of Israel, twelve, according to their names, like the engravings of a signet, every one with his name, according to the twelve tribes.

¹⁵  And they made upon the breastplate chains at the ends, of wreathed work of pure gold.

¹⁶  And they made two ouches of gold, and two gold rings; and put the two rings in the two ends of the breastplate.

¹⁷  And they put the two wreathed chains of gold in the two rings on the ends of the breastplate.

¹⁸  And the two ends of the two wreathed chains they fastened in the two ouches, and put them on the shoulderpieces of the ephod, before it.
