ISB ~ John 12 v40

He has blinded:A reference to Is 6:10.

• Isaiah’s mission to Israel in the eighth century B.C. parallels Jesus’ mission to Israel in the first century A.D. Both confront a rebellious generation whose unbelief calls down the covenant judgment of Yahweh; and, in both cases, God responds to unbelief by blinding and hardening the rebels, making them unresponsive to the warnings of the Prophets. See note on Mk 4:12.
