Exodus 28:6

“And they shall make the ephod, etc.] This was the outermost garment of, all, and was put over the robe; it was a short garment, reaching to the loins, as Kimchi f809; or to the buttocks, as Abarbinel f810; and not to the heels or feet, as Jarchi f811, and Maimonides f812; for Josephus f813 says it was but a cubit long, which was little more than half a yard; he means that part of it which was distinct from the shoulder pieces, and came down from thence: the hinder part of it covered the back, and reached to the middle of the buttocks; and the forepart covered the breast and belly, and with shoulder pieces under the arm holes was buttoned with onyx stones upon the top of the shoulders, and…”

“ephod--It was a very gorgeous robe made of byssus, curiously embroidered, and dyed with variegated colors, and further enriched with golden tissue, the threads of gold being either originally interwoven or afterwards inserted by the embroiderer. It was short--reaching from the breast to a little below the loins--and though destitute of sleeves, retained its position by the support of straps thrown over each shoulder. These straps or braces, connecting the one with the back, the other with the front piece of which the tunic was composed, were united on the shoulder by two onyx stones, serving as buttons, and on which the names of the twelve tribes were engraved, and set in golden encasements.…”

“(Compare Exodus 39:1-31.) Moses is now commanded to commit all that pertains to the offerings made to the Lord in the sanctuary to the exclusive charge of the members of a single family, who were to hold their office from generation to generation. In the patriarchal times, the external rites of worship had generally been conducted by the head of the tribe or family, in accordance with the principle involved in the dedication of the firstborn Exodus 13:2; Numbers 3:12-13. Moses, as the divinely-appointed and acknowledged leader of the nation, had, on a special occasion, appointed those who were to offer sacrifice, and had himself sprinkled the consecrating blood of the victims on the people…”

“The ephod, was the outmost garment of the high - priest; linen ephods were worn by the inferior priests, but this, which the high - priest 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 close to him with a curious girdle of the same stuff. The shoulder pieces were buttoned together with two precious stones set in gold, one on each shoulder. In allusion to this, Christ our high priest appeared to John, girt about the paps with a golden girdle, such as was the curious girdle of the ephod, Rev 1:13. Righteousness is the girdle of his loins. He is girt with strength for the work of our salvation. And as Aaron…”

“28:6-14 The ephod was a kind of apron consisting of front and back pieces joined by shoulder straps (28:7) and secured by a decorative sash (28:8, 27-28). Perhaps it is mentioned first because it was understood to be the distinctive high priestly garment. The fact that Gideon later made a gold ephod (Judg 8:27) suggests that the garment was thought to have special powers.”

“linen: Exo 26:1 Exodus 28:7”

“The first part mentioned of Aaron's holy dress, i.e., of the official dress of the high priest, is the ephod. The etymology of this word is uncertain; the Sept. rendering is ἐπωμίς (Vulg. superhumerale, shoulder-dress; Luther, "body-coat"). It was to be made of gold, hyacinth, etc., artistically woven, - of the same material, therefore, as the inner drapery and curtain of the tabernacle; but instead of having the figures of cherubim woven into it, it was to be worked throughout with gold, i.e., with gold thread. According to Exo 39:3, the gold plates used for the purpose were beaten out, and then threads were cut (from them), to be worked into the hyacinth, purple, scarlet, and byssus. It…”
