John 8:27

They understood not that he spake to them of the Father.
] That sent him, and who was true and faithful to all he had said, whether in a way of promise, or threatening; such was their stupidity, that they did not know that he meant God the Father by him that sent him, so deriving his mission and doctrine from him; their hearts were made fat, and hardened, and their eyes were blinded. The Vulgate Latin version reads, "they did not know that he said, God was his Father"; and so Beza's most ancient copy, and another exemplar of his.
