John 8:19

“Then said they unto him, where is thy Father? etc.] The Persic version adds, “show [him] unto us”: produce this witness boasted of, let us see him; this they said in a sneering, taunting, and insulting manner; where is thy Father? what! he is in Galilee; fetch him from thence; it is Joseph the carpenter you mean; a goodly witness indeed! Jesus answered, ye neither know me nor my Father; if ye had known me, ye should have known my Father also; they did not know the divine original of Christ, that he was the Son of God, and that God was his Father; they greatly boasted of their knowledge of God, but they knew him not; their ignorance of Christ showed it: the knowledge of both go together, and…”

John 8:23”

“8:19 Throughout the festival, Jesus’ audience proved they were in the darkness as they misunderstood him. They wanted to meet Jesus’ father, who is God. Since they did not truly know God, they were unable to understand Jesus.”
