Now as he walked by the sea of Galilee, he saw Simon and Andrew his brother casting a net into the sea: for they were fishers. As he walked by the sea, etc. - See on Matthew 4:18-22 (note).
Andrew his brother - Instead of the common reading, αδελφον αυτου, his brother, the best MSS. and versions have αδελφου του Σιμωνος, the brother of Simon, which should be received into the text. The most eminent critics approve of this reading.
