The name Nathanael is derived from the Hebrew: "Nathanael" a male given name that means "gift of God" (from Hebrew Natan "he gives" + el "God"). Based on this meaning, many have assumed it was not a given name, but a family name.
Bartholomew (Nathanael) was born in Cana of Galilee. (John 21:2).
45 Philip found Nathanael and said to him, "We have found him of whom Moses in the Law and also the prophets wrote, Jesus of Nazareth, the son of Joseph." 46 Nathanael said to him, "Can anything good come out of Nazareth?" Philip said to him, "Come and see." John 1:45-46He was listed as one of Christ's twelve disciples (Matthew 10:2-4; Acts 1:13).
He was honest
7 Jesus saw Nathanael coming toward him and said of him, "Behold, an Israelite indeed, in whom there is no deceit!" (John 1:47)and he was faithful (John 1:49).
Jesus told him "Truly, truly, I say to you, you will see heaven opened, and the angels of God ascending and descending on the Son of Man." (John 1:50:51)He was a witness of the miracle catch of fish and ate with Jesus after his resurrection
2 Simon Peter, Thomas (called the Twin), Nathanael of Cana of Galilee, the sons of Zebedee, and two others of his disciples were together. 3 Simon Peter said to them, "I am going fishing." They said to him, "We will go with you." They went out and got into the boat, but that night they caught nothing. 4 Just as day was breaking, Jesus stood on the shore; yet the disciples did not know that it was Jesus. 5 Jesus said to them, "Children, do you have any fish?" They answered him, "No." 6 He said to them, "Cast the net on the right side of the boat, and you will find some." So they cast it, and now they were not able to haul it in, because of the quantity of fish. 7 That disciple whom Jesus loved therefore said to Peter, "It is the Lord!" When Simon Peter heard that it was the Lord, he put on his outer garment, for he was stripped for work, and threw himself into the sea. John 21:2-7 ESV
