'Parents' in the Bible

And his disciples asked him, saying, Rabbi, who sinned, this man, or his parents, that he should be born blind?

Jesus answered, Neither did this man sin, nor his parents: but that the works of God should be made manifest in him.

The Jews therefore did not believe concerning him, that he had been blind, and had received his sight, until they called the parents of him that had received his sight,

His parents answered and said, We know that this is our son, and that he was born blind:

These things said his parents, because they feared the Jews: for the Jews had agreed already, that if any man should confess him to be Christ, he should be put out of the synagogue.

Therefore said his parents, He is of age; ask him.
