Hebrews 7:21-23

Living Bible

²¹ although he never said that of other priests. Only to Christ he said, “The Lord has sworn and will never change his mind: You are a Priest forever, with the rank of Melchizedek.” ²² Because of God’s oath, Christ can guarantee forever the success of this new and better arrangement.

²³ Under the old arrangement there had to be many priests so that when the older ones died off, the system could still be carried on by others who took their places.
