Since we are now done with the description of all the garments of the High Priest and his Sons, it is no time to add finishing touches to the result. One important aspect of the High Priest garments that I have not covered yet is the size and shape of the Ephod (Vestment).
If you remember, the resulting Ephod so far looked like so:
But the verses of Exodus 28:33-35 state that the Blue Robe that was worn right under the Ephod had Golden Bells that were to serve as special warning sings for the Priest when he was going in/around the Tabernacle. Like so:
Obviously, it is clear that the Ephod could not be covering these Bells as it would render them inoperable, muffling the sound or possibly even preventing them from making any. And since the Bells were located on the bottom portion of the Blue Robe, it is most logical that this part of the Robe was not covered by the Ephod at all. Like so:
Please also note that since the Ephod now would not be covering the bottom portion of the Blue Robe, it is also most likely that, for symmetry reasons, the Ephod also would not cover the parts of the High Priest hands (roughly from the elbow and to the end of each hand). Therefore, the Ephod most likely looked like a thick, woven T-Shirt, main purpose of which was to hold the Breastplate of Judgement and the two "onyx" stones. Also, the colored embroidered Sash was going over the Ephod but only because it would help to secure it upon the High Priest. Like so:
Please also note, that unlike the Sons of Aaron, the White Tunic that was worn under the Blue Robe was completely covered. At this point I do not see any reason why the White Tunic had to be visible at all, but as usual more research is needed to properly size each of these garments.
