8:19 The Pharisees misunderstood Jesus’ claim as a reference to His physical father, and they may have been eager to challenge Him as a child allegedly born out of wedlock. In speaking of His Father, however, Jesus was not talking about Joseph but about God. Knowledge of the Father comes through the Son (1:18; 14:9; 1 John 5:20). The Pharisees’ blindness to Jesus shows that their technical knowledge of the law did not give them the knowledge of God.
