(11) The engravings of a signet.--Compare Note 2 on Exodus 28:9. Signets had been already mentioned in Genesis 38:18; Genesis 38:25; Genesis 41:42. Those of Egypt were for the most part rings, with cylindrical bezels turning upon an axis. Those of Babylonia were cylinders, which were commonly worn by a string round the wrist. The engraving of the Babylonian cylinders is frequently of a very fine quality.

Thou shalt make them to be set in ouches of gold.--The setting intended seems to have been a sort of open or filigree work, such as is very common in Egyptian ornaments of the time. The term "ouche"--more properly "nouch"--is derived from the old French "nouche,"a buckle or clasp (see Skeat's Etymol. Dict., ?5).

Verse 11. - With the work of an engraver. Rather, "an artificer." The engravings of a signet. Signets in Egypt were ordinarily rings, on the bezel of which the name of the owner was inscribed. Some were of solid gold; others with cylindrical bezels of glass or hard stone. On the early use of such signet rings in Egypt see Genesis 41:42. Cylinders, strung round the wrist and engraved with a name and titles, were common in Mesopotamia from B.C. 2000. Ouches of gold. Settings in open-work or filagree seem to be intended - a kind of setting which is very common in Egyptian ornaments.

28:6-14 This richly-wrought ephod was the outmost garment of the high priest; plain linen ephods were worn by the inferior priests. It was a short coat without sleeves, fastened close to the body with a girdle. The shoulder-pieces were buttoned together with precious stones set in gold, one on each shoulder, on which were engraven the names of the children of Israel. Thus Christ, our High Priest, presents his people before the Lord for a memorial. As Christ's coat had no seam, but was woven from the top throughout, so it was with the ephod. The golden bells on this ephod, by their preciousness and pleasant sound, well represent the good profession that the saints make, and the pomegranates the fruit they bring forth.With the work of an engraver in stone,.... Not in common but precious stones: Moses was not to do this himself, as it could not be supposed he should, but he was to employ an engraver, whose business it was, and one that was capable of doing it in a professional manner:

like the engravings of a signet shall thou engrave the two stones with the names of the children of Israel: as in signets or seals, by which impressions are made on wax, the letters or figures are cut deep, that they might on the wax stand out; so it seems the letters of the names of the children of Israel were cut in these stones: this shows that engraving on precious stones is very old, and the ancients indeed are said to excel in this art:

thou shalt make them to be set in ouches of gold; in beazils or sockets, such as precious stones in rings are set in; these with the stones in them served as buttons to fasten together the hinder and fore part of the ephod on the shoulder pieces of it.
