Priestly garments. Notice the elements used for the priests: fine linen cloth, gold thread, and blue, purple, and scarlet thread. Each of these is symbolic for something (of course). Gold is for deity, fine linen is for righteousness or purity, blue represents heaven (God's dwelling), purple indicates royalty, and scarlet is for sacrifice. I found several websites that supported what these colors stand for, but here's one that makes it easy.
Chestpiece. The stones used in the priest's chest piece are the same as the foundation stones in the wall of the New Jerusalem described in Revelation 22. I see an interesting connection. Exodus says the stones in the chestpiece represent the 12 tribes of Israel. But in Revelation 22, the twelve tribes are written on the 12 gates of the New Jerusalem, while the names of the 12 apostles are written on the 12 foundations stones of the walls of the city (same as in the chestpiece). In Revelation 4:4, we read about "elders:" "Twenty-four thrones surrounded him, and twenty-four elders sat on them. They were all clothed in white and had gold crowns on their heads." Who do you suppose the 24 elders are, based on these clues?
Aaron is another Christ-type, and I love this picture we are given of Christ's love for His tribes, for His apostles (above), and also for His people. 28:29 "In this way, Aaron [Jesus also] will carry the names of the tribes of Israel on the sacred chestpiece over his heart when he goes into the Holy Place. This will be a continual reminder that he represents the people when he comes before the Lord."
Did you know that now, believers are considered priests? I used to think only the Jewish believers were given this honor, but read this verse in Revelation 5:9-10: "For you were killed, and your blood has ransomed people for God from every tribe and language and people and nation. And you have caused them to become God's Kingdom and his priests. And they will reign on the earth." As His priests, we should also carry His tribes over our hearts when we enter the Holy Place (pray for Israel).
25:41 "Then the King will turn to those on the left and say, ‘Away with you, you cursed ones, into the eternal fire prepared for the devil and his demons." Have you ever thought about the fact that that hell was not made for people? God prepared hell only for Satan and his demons. It was never God's wish for anyone to end up in hell, and for some reason people don't get that by rejecting the "bridge to life," they send themselves to hell.
