John 8:37-39

Mace(i) 37 I know you are Abraham's offspring; but ye seek to kill me, because my doctrine doth not penetrate into you. 38 what I have learnt from my father, that I tell: and what you have learnt from your father, that you do. 39 they answered him, Abraham is our father. if you were Abraham's children, said Jesus, you would act like Abraham.
