'Discovered' in the Bible

He first looked for and found his own brother Simon and told him, “We have found the Messiah” (which translated means the Christ).

Philip found Nathanael and told him, “We have found the One Moses in the Law and also the Prophets wrote about—Jesus from Nazareth, the son of Joseph [according to public record].”

Look, He is speaking publicly, and they say nothing to Him! Is it possible that the rulers really know that this is the Christ?
