ISB ~ John 12 v41

saw his glory:Alludes to the context of Is 6:10 cited in the preceding verse.

• Isaiah’s prophetic mission began with a vision of Yahweh enthroned in glory, “high and lifted up” (Is 6:1). It is possible that John is connecting this with Isaiah’s later vision of the messianic Servant, who is likewise “exalted and lifted up” (Is 52:13) (CCC 712-13).
