John 9:22-24

22His parents said these things because they feared the Jews, for the Jews had already agreed that if any one confessed him [to be the] Christ, he should be excommunicated from the synagogue.

23On this account his parents said, He is of age: ask him.

24They called therefore a second time the man who had been blind, and said to him, Give glory to 1God: we know that this man is sinful.
