Matthew Poole and continuators on Exodus 28:22

22 And thou shalt make upon the breast-plate chains at the ends , of wreathen work of pure gold.

Some think these are the same with those mentioned, v. 14. But it seems improbable and without example, that God should in this short description, and that within a few verses, give a new and second command concerning the same thing. It may rather seem that these are other chains fastened to the breastplate, as it follows, whereas those chains ver. 14. seem to have been fastened to the ephod, to those ouches made in it for that purpose, ver. 13. And whereas these chains also are fastened in the said ouches ver. 25. two several chains may well enough be fastened in divers parts of each of the ouches, and there seems to be this difference between the chains, those chains mentioned ver. 14. are said to be fastened onely at one end, even to the ouches of the Ephod, whence they might hang down loosely, whereas these are manifestly fastened at both ends, ver. 24, 25.
