SEV Biblia, Chapter 28:11
De obra de grabador en piedra a modo de grabaduras de sello, harás grabar aquellas dos piedras con los nombres de los hijos de Israel; les harás alrededor engastes de oro.
Clarke's Bible Commentary - Exodus 28:11
Verse 11. Like the engravings of a signet] So signets or seals were in use at this time, and engraving on precious stones was then an art, and this art, which was one of the most elegant and ornamental, was carried in ancient times to a very high pitch of perfection, and particularly among the ancient Greeks; such a pitch of perfection as has never been rivalled, and cannot now be even well imitated. And it is very likely that the Greeks themselves borrowed this art from the ancient Hebrews, as we know it flourished in Egypt and Palestine long before it was known in Greece.
Matthew Henry Commentary
Verses 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 shor coat without sleeves, fastened close to the body with a girdle. The shoulder-pieces were buttoned together with precious stones set i 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 wa woven from the top throughout, so it was with the ephod. The golde bells on this ephod, by their preciousness and pleasant sound, wel represent the good profession that the saints make, and the pomegranates the fruit they bring forth.
