Exodus 28:6-8
6 And they shall make the ephod of gold, of blue, and of purple, of scarlet, and fine twined linen, with cunning work. 7 It shall have the two shoulderpieces thereof joined at the two edges thereof; and so it shall be joined together. 8 And the curious girdle of the ephod, which is upon it, shall be of the same, according to the work thereof; even of gold, of blue, and purple, and scarlet, and fine twined linen. 9 And thou shalt take two onyx stones, and grave on them the names of the children of Israel: 10 Six of their names on one stone, and the other six names of the rest on the other stone, according to their birth. 11 With the work of an engraver in stone, like the engravings of a signet, shalt thou engrave the two stones with the names of the children of Israel: thou shalt make them to be set in ouches of gold. 12 And thou shalt put the two stones upon the shoulders of the ephod for stones of memorial unto the children of Israel: and Aaron shall bear their names before the LORD upon his two shoulders for a memorial. 13 And thou shalt make ouches of gold; 14 And two chains of pure gold at the ends; of wreathen work shalt thou make them, and fasten the wreathen chains to the ouches.
Directions are here given concerning the ephod, which was the outmost garment of the high priest. Linen ephods were worn by the inferior priests, 1 Sam. xxii. 18. Samuel wore one when he was a child (1 Sam. ii. 18), and David when he danced before the ark (2 Sam. vi. 14); but this which the high priest only wore was called a golden ephod, because there was a great deal of gold woven into it. It was a short coat without sleeves, buttoned closely to him, with a curious girdle of the same stuff (v. 6-8); the shoulder-pieces were buttoned together with two precious stones set in gold, one on each shoulder, on which were engraven the names of the children of Israel, v. 9-12. In allusion to this, 1. Christ our high priest appeared to John girt about the breast with a golden girdle, such as was the curious girdle of the ephod, Rev. i. 13. Righteousness is the girdle of his loins (Isa. xi. 6), and should be of ours, Eph. vi. 14. He is girt with strength for the work of our salvation, and is ready for it. 2. The government is said to be upon his shoulders (Isa. ix. 6), as Aaron had the names of all Israel upon his shoulders in precious stone. He presents to himself and to his Father a glorious church, Eph. v. 27. He has power to support them, interest to recommend them, and it is in him that they are remembered with honour and favour. He bears them before the Lord for a memorial (v. 12), in token of his appearing before God as the representative of all Israel and an advocate for them.
