“These words spake Jesus in the treasury, as he taught in the temple: and no man laid hands on him; for his hour was not yet come.”
John 8:20 — Greek Interlinear
Church Fathers on John 8:20
Those who had heard out Lord say, You judge after the flesh, showed that they did so; for they understood what He said of His Father in a carnal sense: Then said they to Him; Where is Your Father? meaning, We have heard you say, I am not alone, but I and the Father that sent Me. We see you alone; prove to us then that Your Father is with You.
Some remark that this is said in contumely and contempt; to insinuate either that He is born of fornication, and knows not who His Father is; or as a slur on the low situation of His father, i.e. Joseph; as if to say, Your father is an obscure, ignoble person; why do you so often mention him? So because they asked the question, to tempt Him, not to get at the truth, Jesus answered, You neither know Me, nor My Father.
He tells them, it is of no avail for them to say they know the Father, if they do not know the Son.
