Exodus 28:9

7It shall have two shoulder straps joined to the two ends of it, that it may be joined together.

8The skillfully woven band, which is on it, shall be like its work and of the same piece; of gold, blue, purple, scarlet, and fine twined linen.

9You shall take two onyx stones, and engrave on them the names of the children of Israel.

10Six of their names on the one stone, and the names of the six that remain on the other stone, in the order of their birth.

11With 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.
