Matthew 4:21

Καὶ προβὰς ἐκεῖθεν εἶδεν ἄλλους δύο ἀδελφούς, Ἰάκωβον τὸν τοῦ Ζεβεδαίου καὶ Ἰωάννην τὸν ἀδελφὸν αὐτοῦ, ἐν τῷ πλοίῳ μετὰ Ζεβεδαίου τοῦ πατρὸς αὐτῶν καταρτίζοντας τὰ δίκτυα αὐτῶν· καὶ ἐκάλεσεν αὐτούς.

And going on from there, he saw two other brothers, Jacob the son of Zebedee, and John his brother, in a boat with Zebedee their father, mending their nets; and he called them.
