'Brothers' in the Bible

And walking by the sea of Galilee, he saw two brothers, Simon called Peter, and Andrew his brother, casting a net into the sea, for they were fishers;

And going on thence he saw other two brothers, James the son of Zebedee and John his brother, in the ship with Zebedee their father, mending their trawl-nets, and he called them;

And the ten, having heard of it, were indignant about the two brothers.
