Exodus 30:18 Thou shalt also make a laver of brass, and his foot also of brass, to wash withal: and thou shalt put it between the tabernacle of the congregation and the altar, and thou shalt put water therein. 19 For Aaron and his sons shall wash their hands and their feet thereat:
[Patriarchs & Prophets pp 350>351] They were to leave their shoes in the court before entering the sanctuary, and also to wash both their hands and their feet before ministering in the tabernacle or at the altar of burnt offering. Thus was constantly taught the lesson that all defilement must be put away from those who would approach into the presence of God. The garments of the high priest were of costly material and beautiful workmanship, befitting his exalted station.
In addition to the linen dress of the common priest, he wore a robe of blue, also woven in one piece. Around the skirt it was ornamented with golden bells, and pomegranates of blue, purple, and scarlet. Outside of this was the ephod, a shorter garment of gold, blue, purple, scarlet, and white. It was confined by a girdle of the same colors, beautifully wrought. The ephod was sleeveless, and on its gold-embroidered shoulder pieces were set two onyx stones, bearing the names of the twelve tribes of Israel.
Over the ephod was the breastplate, the most sacred of the priestly vestments. This was of the same material as the ephod. It was in the form of a square, measuring a span, and was suspended from the shoulders by a cord of blue from golden rings. The border was formed of a variety of precious stones, the same that form the twelve foundations of the City of God. Within the border were twelve stones set in gold, arranged in rows of four, and, like those in the shoulder pieces, engraved with the names of the tribes.
Exodus 28:4 And these are the garments which they shall make; a breastplate, and an ephod, and a robe, and a broidered coat, a mitre, and a girdle: and they shall make holy garments for Aaron thy brother, and his sons, that he may minister unto me in the priest's office.
May God add His blessing to the study of His word. “Good night” and God bless!
