Hebrews 10:9-14

then hath he said, Lo, I am come to do thy will. He taketh away the first, that he may establish the second. By which will we have been sanctified through the offering of the body of Jesus Christ once for all. And every priest indeed standeth day by day ministering and offering oftentimes the same sacrifices, the which can never take away sins: but he, when he had offered one sacrifice for sins for ever, sat down on the right hand of God; henceforth expecting till his enemies be made the footstool of his feet. For by one offering he hath perfected for ever them that are sanctified.
