Should "Bible" = "Word of God"?

The English word “Bible”? correct. He never mentioned that. Of course, neither does anything else in the Bible itself ever mention “the Bible.”

He often enough mentioned the Scripture; and his references go well beyond only those “quotes” where God is explicitly speaking, for instance his quotes of psalms.

And he said to them, “You have a fine way of rejecting the commandment of God in order to establish your tradition! For Moses said, Honor your father and your mother’; and, Whoever reviles father or mother must surely die.’ But you say, ‘If a man tells his father or his mother, “Whatever you would have gained from me is Corban”’ (that is, given to God)— then you no longer permit him to do anything for his father or mother, thus making void the word of God by your tradition that you have handed down. And many such things you do.”
