John 12:39-43

For this reason they could not believe, for Isaiah said again,

“He has blinded their eyes and He hardened their heart, so that they will not see with their eyes and understand with their heart, and be converted, and so I will not heal them.”

These things Isaiah said because he saw His glory, and he spoke about Him.

Nevertheless many, even of the rulers, believed in Him, but because of the Pharisees they were not confessing Him, so that they would not be excommunicated from the synagogue;

for they loved the approval of people rather than the approval of God.
