'Prophets' in the Bible

Philip found Nathanael, and said to him, "We have found him, of whom Moses in the law, and the prophets, wrote: Jesus of Nazareth, the son of Joseph."

It is written in the prophets, 'They will all be taught by God.' Therefore everyone who hears from the Father, and has learned, comes to me.

Then the Jews said to him, "Now we know that you have a demon. Abraham died, and the prophets; and you say, 'If a man keeps my word, he will never taste of death.'

Are you greater than our father, Abraham, who died? The prophets died. Who do you make yourself out to be?"
