'Brother' in the Bible

One of the two that heard John'speak , and followed him, was Andrew, Simon Peter's brother.

He findeth first his own brother Simon, and saith unto him, We have found the Messiah (which is, being interpreted, Christ).

One of his disciples, Andrew, Simon Peter's brother, saith unto him,

And it was that Mary who anointed the Lord with ointment, and wiped his feet with her hair, whose brother Lazarus was sick.

and many of the Jews had come to Martha and Mary, to console them concerning their brother.

Martha therefore said unto Jesus, Lord, if thou hadst been here, my brother had not died.

Jesus saith unto her, Thy brother shall rise again.

Mary therefore, when she came where Jesus was, and saw him, fell down at his feet, saying unto him, Lord, if thou hadst been here, my brother had not died.
