(Part 3) A priest forever according to the order of Melchizedek - כהן גדול על־דברתי מלכי־צדק

“The LORD has sworn and will not change His mind, “You are a priest forever according to the order of Melchizedek.“ Psalms 110:4 Who is this priest that holds His priesthood permanently ? Is this the New Covenant of which God has spoken in Jeremiah 31:31 ?
