28:20 and the fourth row, a chrysolite, an onyx, and a jasper. ¹  They are to be enclosed in gold in their filigree settings.

Exodus 28:39

28:39 You are to weave ²  the tunic of fine linen and make the turban of fine linen, and make the sash the work of an embroiderer.

[28:20]  ¹ sn U. Cassuto (Exodus, 375-76) points out that these are the same precious stones mentioned in Ezek 28:13 that were to be found in Eden, the garden of God. So the priest, when making atonement, was to wear the precious gems that were there and symbolized the garden of Eden when man was free from sin.

[28:39]  ² tn It is difficult to know how to translate וְשִׁבַּצְּתָּ (vÿshibbatsta); it is a Piel perfect with the vav (ו) consecutive, and so equal to the imperfect of instruction. Some have thought that this verb describes a type of weaving and that the root may indicate that the cloth had something of a pattern to it by means of alternate weaving of the threads. It was the work of a weaver (39:27) and not so detailed as certain other fabrics (26:1), but it was more than plain weaving (S. R. Driver, Exodus, 310). Here, however, it may be that the fabric is assumed to be in existence and that the action has to do with sewing (C. Houtman, Exodus, 3:475, 517).
