Exodus 28:11 Meaning and Commentary

Exodus 28:11

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.

10 six of their names on the one stone, and the names of the remaining six on the second stone, according to their births;
11 the work of an engraver in stone, openings of a signet, thou dost open the two stones by the names of the sons of Israel; turned round, embroidered [with] gold, thou dost make them.
12 `And thou hast set the two stones on the shoulders of the ephod -- stones of memorial to the sons of Israel -- and Aaron hath borne their names before Jehovah, on his two shoulders, for a memorial.
13 `And thou hast made embroidered things of gold,
