John 12:37-38
Context12:37 Although Jesus 1 had performed 2 so many miraculous signs before them, they still refused to believe in him, 12:38 so that the word 3 of Isaiah the prophet would be fulfilled. He said, 4 “Lord, who has believed our message, and to whom has the arm of the Lord 5 been revealed?” 6
[12:37] 1 tn Grk “he”; the referent (Jesus) has been specified in the translation for clarity.
[12:38] 5 tn “The arm of the Lord” is an idiom for “God’s great power” (as exemplified through Jesus’ miraculous signs). This response of unbelief is interpreted by the author as a fulfillment of the prophetic words of Isaiah (Isa 53:1). The phrase ὁ βραχίων κυρίου (Jo braciwn kuriou) is a figurative reference to God’s activity and power which has been revealed in the sign-miracles which Jesus has performed (compare the previous verse).
