HEB 7:27

27 [The other] Supreme Priests need to sacrifice [animals] day by day [as well as year by year]. They do this, firstly, [to atone] for their own sins, and then [to atone for other] people [who have sinned]. [But because Jesus never sinned], he does not need to atone for his own sin. The only thing [he needed to do to save people] was to sacrifice himself once!
