2"You shall make holy garments for Aaron your brother, for glory and for beauty.
3"You shall speak to all the skillful persons whom I have endowed with the spirit of wisdom, that they make Aaron's garments to consecrate him, that he may minister as priest to Me.
The entire chapter of Exodus 28 describes in detail the clothing to be fabricated and worn by Aaron and his sons as they ministered in the tabernacle as priests to God. These garments were holy or set apart for glory and beauty. The Old Testament word for glory means weighty as in valuable or more precious. You can picture a set of scales with feathers on one side and a pile of gold bars on the other. Glory would be the gold bars that would weigh down the one side of the scales far outweighing the feathers and would also be much more valuable. The word for beauty used in the text can mean ornament, honor, majesty as well as beauty. Therefore, these special clothes were made to be worn only for one purpose, for the priests to serve God in conjunction with the tabernacle. These garments symbolized the weightiness or preciousness of this service and the honor, majesty and beauty of ministering to our God.
According to the New Covenant, Jesus is now our High Priest ministering to God in the heavenly tabernacle.
