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.

Exodus 28:11 In-Context

9 You shall take two onyx stones, and engrave on them the names of the sons of Israel,
10 six of their names on the one stone, and the names of the remaining six on the other stone, in the order of their birth.
11 As a jeweler engraves signets, so shall you engrave the two stones with the names of the sons of Israel. You shall enclose them in settings of gold filigree.
12 And you shall set the two stones on the shoulder pieces of the ephod, as stones of remembrance for the sons of Israel. And Aaron shall bear their names before the LORD on his two shoulders for remembrance.
13 You shall make settings of gold filigree,
