John 1:47

Jesus declared that Nathanael was an Israelite in whom there was no deceit. Nathanael was the opposite of the original Israel, namely, Jacob, who was very deceitful (Genesis 27:35-36; Genesis 28:12; cf. John 1:51). Therefore Jesus virtually said that Nathanael was an Israelite in whom there was no Jacob. Jesus evidently knew about Nathanael before Philip brought him to Him, as He knew the other men whom He later formally called to be His disciples.
