Exodus 28:4 - Ellicott's Commentary On The Whole Bible

(4). These are the garments. — The garments peculiar to the high priest are taken first, and described with great elaboration in thirty-six verses (4-39). The most conspicuous was the breastplate, described in Exodus 28:13-30, and here mentioned first of all. Next to this came the peculiar vestment called the “ephod,” a sort of jerkin or waistcoat, upon which the breastplate was worn (described in Exodus 28:6-12). Under the ephod was the long robe of blue, called “the robe of the ephod,” which may be considered as the main garment, and which is described in Exodus 28:31-35. Upon his head the high priest wore a “mitre” or turban (described in Exodus 28:36-38); and inside his “robe” he wore a linen shirt or tunic, secured by a girdle (Exodus 28:39). Underneath the tunic he wore linen drawers (Exodus 28:42-43). Nothing is said as to any covering for his feet; but it is probable that they were protected by sandals.
