Exodus 28

The things I noticed in this chapter were the repetition of the colors for use in priestly garments and the use of gemstones in connection or as representations of the twelve tribes of Israel. I wonder if there were specific meanings behind the colors and the particular stones for each of the tribes, but the text does very little to illuminate any reasons other than that this was God's will. If any readers out there have thoughts or know of resources on this topic, please leave a comment.
