But this, for that he continueth for ever, hath an everlasting priesthood,
but this man, because he continueth ever, hath an unchangeable priesthood.
But He holds His priesthood unchangeably, because He lives on forever.
but he, because he abideth for ever, hath his priesthood unchangeable.
In contrast, he holds the office of priest permanently because he continues to serve forever.
But this man, because he continues forever, has an everlasting priesthood.
