ISB ~ Mark 10 v45

for many:The expression is used idiomatically to mean “for all”. It indicates that Jesus will die, not just for some, but for the sins of the entire world (2 Cor 5:14; 1 Jn 2:2).

• Here and elsewhere Jesus interprets his Passion as the fulfillment of the Isaian prophecy about the Suffering Servant (Is 52:13-53:12; Lk 22:37). Pouring out his life “for many” recalls how the messianic Servant will make “many” righteous and remit the sins of “many” by bearing their afflictions (Is 53:11-12; Rom 5:19).
