New English Translation

Exodus 28:39 tn It is difficult to know how to translate וְשִׁבַּצְתָּ (v^eshibbatsta); 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).
Exodus 28:40 sn This refers to a band of linen wrapped around the head, forming something like a brimless convex cap, resembling something like a half egg. It refers to the headgear of ordinary priests only (see S. R. Driver, Exodus, 310-11).
