Ouches of gold - משבצת mishbetsoth, strait places, sockets to insert the stones in, from שבץ shabats, to close, enclose, straiten.

Socket, in this place, would be a more proper translation, as ouch cannot be traced up to any legitimate authority. It appears sometimes to signify a hook, or some mode of attaching things together.

And thou shalt make ouches of gold. Or sockets of gold, to put the two onyx stones in, Exodus 28:11 for of other ouches we read not, excepting the enclosings, in which the twelve stones of the breastplate were set, Exodus 28:20 and these are again mentioned because of the chains to be fastened to them, of which in the following verse.

There were also to be made for the ephod two (see Exodus 28:25) golden plaits, golden borders (probably small plaits in the form of rosettes), and two small chains of pure gold: "close shalt thou make them, corded" (lit., work of cords or strings), i.e., not formed of links, but of gold thread twisted into cords, which were to be placed upon the golden plaits or fastened to them. As these chains served to fasten the choshen to the ephod, a description of them forms a fitting introduction to the account of this most important ornament upon the state-dress of the high priest.

And thou shalt make ouches of gold;

28:6-14 This richly-wrought ephod was the outmost garment of the high priest; plain linen ephods were worn by the inferior priests. It was a short coat without sleeves, fastened close to the body with a girdle. The shoulder-pieces were buttoned together with precious stones set in gold, one on each shoulder, on which were engraven the names of the children of Israel. Thus Christ, our High Priest, presents his people before the Lord for a memorial. As Christ's coat had no seam, but was woven from the top throughout, so it was with the ephod. The golden bells on this ephod, by their preciousness and pleasant sound, well represent the good profession that the saints make, and the pomegranates the fruit they bring forth.
