And like a robe You will roll them up;
Like a garment they will be changed.
But You are the same [forever],
And Your years will never end.”

(for those Levites who formerly became priests [received their office] without [its being confirmed by the taking of] an oath, but this One [was designated] with an oath through the One who said to Him,

“The Lord has sworn
And will not change His mind or regret it,
‘You (Christ) are a Priest forever’”).
