Exodus 39:2-7
The Ephod
39:2 He made the ephod of gold, blue, purple, scarlet, and fine twisted linen.
39:3 They hammered the gold into thin sheets and cut it into narrow strips to weave them into the blue, purple, and scarlet yarn, and into the fine linen, the work of an artistic designer.
39:4 They made shoulder pieces for it, attached to two of its corners, so it could be joined together.
39:5 The artistically woven waistband of the ephod that was on it was like it, of one piece with it, of gold, blue, purple, and scarlet yarn and fine twisted linen, just as the Lord had commanded Moses.
39:6 They set the onyx stones in gold filigree settings, engraved as with the engravings of a seal with the names of the sons of Israel.
39:7 He put them on the shoulder pieces of the ephod as stones of memorial for the Israelites, just as the Lord had commanded Moses.
