John 12 - CSB Apologetics Study Bible

12:12-19 The way people acted on Palm Sunday contrasted dramatically with the crowd’s clamoring for Jesus’s crucifixion five days later. Some in the two crowds would have differed, but this was also the last time the onlookers thought that maybe Jesus was going to assume an earthly kingship and free his nation. When it became clear that was not his purpose, disillusionment and hostility reappeared.

12:41 In context, Is 6:10 wasn’t even a prediction, much less one about Jesus. But Jews recognized typological as well as predictive prophecy. Typology is the repetition of a significant pattern of God’s activity in redemptive history that can properly be ascribed only to him. Isaiah did make predictions about the Messiah on numerous occasions, and the context of Is 6 looked beyond the present, evil generation of Isaiah, so it is understandable why John would believe that Isaiah previewed Jesus’s glory.
