Hebrews 7:21

JMNT(i) 21 for on the one hand there are indeed men that have become priests apart from a sworn oath, yet on the other hand, He [became one] with an oath sworn through, and by means of, the One saying to Him, "The Lord [= Yahweh] swore (or: swears) and shall not be regretting (having after-care), 'You are a Priest on into the Age [other MSS add: according to and in line with the order and succession of Melchizedek] '." [Ps. 110:4]
