'Brother' in the Bible

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

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

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

(It was that Mary which anointed the Lord with ointment, and wiped his feet with her hair, whose brother Lazarus was sick.)

And many of the Jews came to Martha and Mary, to comfort them concerning their brother.

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

Jesus saith unto her, Thy brother shall rise again.

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