I notice how quickly you can get off track.
Deal with Hebrews first, and then we can talk about Zechariah, the priesthood, prophecies, etc in the light of what we learn from Hebrews and the rest of the NT.
Hebrews is not in a vacuum. You have to take the Bible as a whole. I am on track. You are out of context.
I've noticed whenever these dispensational topics are being discussed, the emphasis is always on the Old Testament to the very real exclusion of the New Testament. It's almost as if they stopped reading right before Matthew.
Every word of Hebrews denies the dispensational error of a reconstructed blood Israel. The only blood that matters is the blood of Christ. The only covenant now in place is the New Covenant.
"In that he saith, A new covenant, he hath made the first old. Now that which decayeth and waxeth old is ready to vanish away." -- Hebrews 8:13
