Matthew 4:18

“And Jesus walking by the sea of Galilee, etc.] Not for his recreation and diversion, or by accident: but on purpose to look out for, and call some, whom he had chosen to be his disciples. And as he was walking about, to and fro, he “saw two” persons; and as soon as he saw them, he knew them to be those he had determined to make his apostles: and these are described by their relation to each other, “brethren”; not merely because they were of the same nation, or of the same religion, or of the same employ and business of life, but because they were of the same blood; and by their names, “Simon called Peter, and Andrew his brother”.
