Hebrews 7:27

Who needeth not daily, as those high priests - As the Jewish priests. This is an additional circumstance introduced to show the superior excellency of the High Priest of the Christian profession, and to show also how he was suited to our wants. The Jewish high priest was a sinful man. He had the same fallen and corrupt nature as others. He needed an expiatory sacrifice for his own sins as really as they did for theirs. When he approached God to offer sacrifice, it was needful to make an atonement for himself, and when all was done it was still a sacrifice offered by a sinful man. But it was not so in the case of Jesus. He was so holy that he needed no sacrifice for himself, and all that he did was in behalf of others. Besides, it was necessary that the sacrifices in the Jewish service should be constantly repeated. They were imperfect. They were mere types and shadows. They who offered them were frail, sinful men. It became necessary, therefore, to repeat them every day to keep up the proper sense of their transgressions, and to furnish a suitable acknowledgment of the tendency to sin alike among the people and the priests. Neither in the nature of the offering, nor in the character of those who made it, was there any sufficient reason why it should cease to be offered, and it was therefore repeated day by day. But it was not so with the Lord Jesus. The offering which he made, though presented but once, was so ample and perfect that it had sufficient merit for all the sins of the world, and needed never to be repeated. It is not probable that the Jewish high priest himself personally officiated at the offering of sacrifice every day; but the meaning here is, that it was done daily, and that there was need of a daily sacrifice in his behalf. As one of the Jewish people, the sacrifice was offered on his account as well as on the account of others - for he partook of the common infirmities and sinfulness of the nation.

For this he did once - That is, once for all - ἐφάπαξ ephapax. He made such an atonement that it was not needful that it should be repeated. Thus, he put an end to sacrifice, for when he made the great atonement it was complete, and there was no need that any more blood should be shed for human guilt.
