Hebrews 10:12

¹⁰ By the which will we are sanctified through the offering of the body of Jesus Christ once for all.

¹¹ And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins:

But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God;

¹³ From henceforth expecting till his enemies be made his footstool.

¹⁴ For by one offering he hath perfected for ever them that are sanctified.

Do read the surrounding verses too, because the context often says more than a single verse.
