Exodus 28:4

28:4 Now these are the garments that they are to make: a breastpiece, ¹  an ephod, ²  a robe, a fitted ³  tunic, a turban, and a sash. They are to make holy garments for your brother Aaron and for his sons, that they may minister as my priests.

Exodus 28:12

28:12 You are to put the two stones on the shoulders of the ephod, stones of memorial for the sons of Israel, and Aaron will bear their names before the Lord on his two shoulders for a memorial. ⁴ 

[28:4]  ¹ sn The breastpiece seems to have been a pouch of sorts or to have had a pocket, since it was folded in some way (28:16; 39:9) and contained the Urim and Thummim (Exod 28:30; Lev 8:8).

[28:4]  ² sn The word “ephod” is taken over directly from Hebrew, because no one knows how to translate it, nor is there agreement about its design. It refers here to a garment worn by the priests, but the word can also refer to some kind of image for a god (Judg 8:27).

[28:4]  ³ tn The word תָּשְׁבֵּץ (tashbets), which describes the tunic and which appears only in this verse, is related to a verb (also rare) of the same root in 28:39 that describes making the tunic. Their meaning is uncertain (see the extended discussion in C. Houtman, Exodus, 3:473-75). A related noun describes gold fasteners and the “settings,” or “mountings,” for precious stones (28:11, 13, 14, 20, 25; 36:18; 39:6, 13, 16, 18; cf. Ps 45:14). The word “fitted” in 28:4 reflects the possibility that “the tunic is to be shaped by sewing, … so that it will fit tightly around the body” (C. Houtman, Exodus, 3:475).

[28:12]  ⁴ sn This was to be a perpetual reminder that the priest ministers on behalf of the twelve tribes of Israel. Their names would always be borne by the priests.
