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.’”
The LORD has sworn and will not change His mind: “You are a priest forever in the order of Melchizedek.”
For it is testified: “You are a priest forever in the order of Melchizedek.”
Men swear by someone greater than themselves, and their oath serves as a confirmation to end all argument.
Moreover, the Glory of Israel does not lie or change His mind, for He is not a man, that He should change His mind.”
