Contemporary English Version (CEV)
Here, the preacher makes a transition from speaking of Melchizedek, the ancient priest, to Jesus Christ, the new priest. Jesus doesn't come from the tribe of Levi, which was the traditional priestly tribe. Instead, Jesus comes from the tribe of Judah, which was the tribe of David, the tribe of Kings. See, Jesus wasn't just a priest, passing along our offerings and communicating what God had to say to us. Jesus was also a King, and so he had power, the ability to change things. Unlike some self-concerned kings, Jesus was more concerned about the people over which he ruled than himself.
Because of this, Jesus made the perfect sacrifice, and when he rose from the dead, he did so with the power to rule over all creation. He was the priest who repaired our relationship with God, and he was the King who ruled in power for us! The King laid himself down so that you might join with him in his realm.
