The influence of Isaiah on John's gospel has long been recognized but has not received monograph-length attention. This work is a beginning attempt to fill that void. It is argued that John 12:1-43 mirrors Isa 52:7-53:1, highlighting Jesus' identity as Servant and announcing that the Isianic new exodus is secured by Jesus' rejection/death. John's contextual reading of Isa 52-53 has fueled much Johannine theology, Christology, and ecclesiology.
