John 8:19

Then said they They said therefore.

Where is thy Father? They do not ask -who" but -where;" they know well enough by this time the meaning of Christ's frequent reference to -Him that sent me:" John 5:23-24; John 5:30; John 5:37-38; John 6:38-40; John 6:44; John 7:16; John 7:18; John 7:28; John 7:33. They ask, therefore, in mockery, what Philip (John 14:8) asks with earnest longing, - Shew us the Father:we see one of Thy two witnesses; shew us the other."

if ye had known me, &c. Better, If ye knew Me, ye would know, &c. (There is a similar error John 5:46). It is in the Son that the Father reveals Himself. Comp. John 14:9; John 16:3; and for the construction comp. John 8:42.
