John 9:18-19

The Jews in view are the Pharisees (John 9:13). Evidently they chose to interview the healed man’s parents because they could not unite on a decision about Jesus. They wanted more information from people closer to him than just his neighbors (John 9:8). Only his parents could affirm that he had been truly blind from birth. If he had not been, the Pharisees could dispute Jesus’ miracle.
