<p>7:28 <i>For the law appoints as high priests men who have weakness, but the word of the oath, which came after the law, appoints the Son who has been perfected forever</i>- See on :27. Sin brings death, so the eternal priest appointed by the word of God's oath in Ps. 110:4 had to be not only eternal but also sinless. There could therefore be no other candidate for this priest than the Lord Jesus. The contrast between the moral weakness of the priests and the perfection of God's Son is further reason to understand &quot;<i>this </i>He did&quot; in :27 as referring solely to His sacrifice for &quot;the people&quot;. The Lord's 'perfecting' was in the supreme moral perfection He achieved on the cross (see on 5:8,9). That acme of utter perfection, attained within a body covered in blood and spittle, dying in agony on a tree trunk, tormented by flies and barking dogs on a hill outside Jerusalem on a Friday afternoon, on a day in April, 2000 or so years ago... has as it were been set in stone eternally. The perfection attained is &quot;forever&quot;. Our far weaker spiritual growth will likewise be eternally set in stone.</p>
