A star will rise from Jacob; a scepter will emerge from Israel.
So, we see that while the priesthood of the Levites was established by the law, the priesthood of Jesus was established through the power of an indestructible life that could only be from the Creator. It was decided before the earth was formed. Jesus would be the final and perfect blood sacrifice for all the sin of the world. He was not, can not, and will not be destroyed or defeated. What Adam gave up in Eden, Jesus took back with His death and resurrection.
Now, we celebrate His birth, but that truly was just the beginning!
