ציטירנדיקער פּירוש אויף שמות 25:7

onyx stones and filling stones on the model of the Tabernacle (Ex. 25:7): “Onyx stones and filling stones, etc.”

ולקחת את שתי אבני שהם, "You are to take the two Shoham-stones, etc." The word את in this connection needs explaining. Perhaps the expression is to draw our attention to the previously mentioned Shoham-stones at the beginning of Parshat Terumah (25,7). The meaning of our verse then would be: "you shall take the two Shoham-stones which I have already commanded you to bring (as gifts)." This would account for the מתג, hyphen, between the words אבני and שהם, i.e. why only these two gemstones have been singled out here by name. These two stones performed a function additional to that of the gemstones called אבני מלואים, "stones to be set" (where the Torah did not employ the hyphen).

Well set in their fullness. All this is an expression of beauty. They neither protrude excessively nor are they sunken, but they are well set מִלֵּאת in their socket. (Other editions: the eye according to the socket.) The literal meaning parallels the allegorical meaning. It מִלֵּאת is a term used for anything made to fill a socket which is made for it as a setting, as in, “stones for setting מִלֻּאִים,”⁴³Shemos 25:7. [and as in,] “And you shall set וּמִלֵּאתָ into it settings מִלֻּאַת of stone.”⁴⁴Ibid. 28:17.
