Hebrews 7:21
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
(For those priests were made without an oath (note: Or, without swearing of an oath); but this with an oath by him that said unto him, The Lord sware and will not repent, Thou art a priest for ever after the order of Melchisedec:)
but Jesus became a priest with an oath by the One who said to Him: “The Lord has sworn and will not change His mind: ‘You are a priest forever (note: Psalm 110:4).’”
