<p>7:27 <i>Who needs not to offer up sacrifices daily, like those high priests, first for his own sins and then for those of the people. For this he did once for all, when he offered up himself</i>- &quot;This he did once&quot; is a contrast with how the old High Priest offered &quot;this&quot; daily Jesus did it only &quot;once&quot;. The reference to &quot;first for his own sins, then for the people's&quot; is as it were in parenthesis, a throw away comment, to indicate again the inferiority of the old High Priests who themselves were sinners and therefore needed to offer for their own sins as well as those of God's people. My own suspicion that Paul was the author of Hebrews is based upon the style of writing we have there which we see in Paul elsewhere- so often, a comment is made in passing like this example of commenting that the old Priests had to offer for their own sins too. This kind of style is typical of Paul, Ephesians and Colossians are full of this kind of thing- making an argument, but throwing in a comment in the midst of it, a kind of aside, which often phases the reader.</p><p>It is not the day of atonement which is in view here, because the contrast is with the &quot;daily&quot; offerings of the priests. A sincere priest would have offered daily sin offerings for himself as well as for the people. The Lord Jesus didn't need to do this; the parallels with the Levitical priesthood are by way of both contrast and similarity. They stood; He sits. They offered animals, He offered &quot;Himself&quot;. But as He offered for &quot;the people&quot; so too did the mortal priests; but He did so once, whereas they did so daily. They offered for their own wins too; He did not. If the Lord in any sense had needed to offer for His own &quot;sins&quot;, He would have had to do so daily. But He offered only one offering, for us. That Christ died for <i>our</i> sins according to the scriptures is the clear emphasis of the entire Biblical revelation. &quot;<i>This</i> He did&quot; refers to His offering for the people, for us; and not for His own 'sins'. This point is underlined in the next verse, which notes that the priests were morally weak, whereas the Son of God is perfect and shall be forever, unable to sin.</p>
