Exodus 28:4

4 Forsooth these shall be the clothes, which they shall make; they shall make a rational, that is, an ouch upon the breast, in which doom and truth shall be written, and a cloak on the shoulders, a coat, and a strait linen cloth, a mitre, and a girdle; holy clothes to Aaron, thy brother, and to his sons, that they be set in priesthood to me. (And these shall be the clothes, which they shall make; they shall make a breast-piece, that is, a pouch, or a pocket, upon the breast, in which shall be carried the Urim and the Thummim, and an ephod, a robe, and an embroidered linen shirt, or tunic, a turban, and a sash; these shall be the holy clothes for thy brother Aaron, and for his sons, when they serve as my priests.)

Exodus 28:4 Meaning and Commentary

Exodus 28:4

And these are the garments which they shall make
Some for Aaron and some for his sons, some peculiar to the high priest, and others in common to him and other priests:

a breastplate, and an ephod, and a robe, and a broidered coat, a mitre,
and a girdle;
of each of which, with others, there is a more particular account in this chapter, and will be observed in their order:

and they shall make holy garments for Aaron thy brother, and his sons:
as those before mentioned, with some others not mentioned; some for Aaron only, and others that were to be worn by his sons also:

that he may minister unto me in the priest's office;
these were absolutely necessary to the execution of the priestly office, and an essential qualification for it, and without which it was not lawful to serve in it.

Exodus 28:4 In-Context

2 And thou shalt make an holy cloth to Aaron, thy brother, into glory and fairness. (And thou shalt make holy clothes for thy brother Aaron, for his glory and beauty, or for his glory and grandeur.)

3 And thou shalt speak to all [the] wise men in heart, which I have filled with the spirit of prudence, that they make clothes to Aaron (so that they make clothes for Aaron), in which he shall be hallowed, and shall minister to me.

4 Forsooth these shall be the clothes, which they shall make; they shall make a rational, that is, an ouch upon the breast, in which doom and truth shall be written, and a cloak on the shoulders, a coat, and a strait linen cloth, a mitre, and a girdle; holy clothes to Aaron, thy brother, and to his sons, that they be set in priesthood to me. (And these shall be the clothes, which they shall make; they shall make a breast-piece, that is, a pouch, or a pocket, upon the breast, in which shall be carried the Urim and the Thummim, and an ephod, a robe, and an embroidered linen shirt, or tunic, a turban, and a sash; these shall be the holy clothes for thy brother Aaron, and for his sons, when they serve as my priests.)

5 And they shall take gold, and jacinth, and purple, and red silk twice-dyed, and bis (and fine linen);

6 forsooth they shall make the cloak on the shoulders of gold, and of jacinth, and of purple, and of red silk twice-dyed, and of bis folded again, by embroidery work of diverse colours [with needlework of diverse colours]. (and they shall make the ephod out of gold, and jacinth, and purple, red silk twice-dyed, and finely woven linen, and embroider it with diverse colours.)
