Final answer:
Philip said to Nathanael, "We have found the one Moses wrote about in the Law, and about whom the prophets also wrote—Jesus of Nazareth, the son of Joseph."
Step-by-step explanation:
When Philip found Nathanael, he said to him, "We have found the one Moses wrote about in the Law, and about whom the prophets also wrote—Jesus of Nazareth, the son of Joseph." This can be found in the Gospel of John 1:45-46. Philip's statement to Nathanael about finding Jesus was his way of introducing him to the Messiah they had been waiting for.
