Hebrews 7:27
He does not need to offer up [animal] sacrifices every day like those head priests did [Note: The head priest here is represented as being in charge of the daily sacrifices offered by the other priests], first for His own sins and then for the people's sins. For He did this once for all time when He offered up Himself [on the cross].
