Hebrews 10:12

“but he, when he had offered one sacrifice for sins forever, sat down on the right hand of God;”

Verse in context — Hebrews 10

by which will we have been sanctified through the offering of the body of Jesus Christ once for all.

Every priest indeed stands day by day serving and often offering the same sacrifices, which can never take away sins,

but he, when he had offered one sacrifice for sins forever, sat down on the right hand of God;

from that time waiting until his enemies are made the footstool of his feet.

For by one offering he has perfected forever those who are being sanctified.

Jesus as the ultimate High Priest and fulfillment of the Old Covenant.
