'Brother' in the Bible
Andrew, Simon Peter's brother, was one of the two who heard John's exclamation and followed Jesus.
He first found his own brother Simon, and said to him, "We have found the Messiah!" --that is to say, the Anointed One.
One of His disciples, Andrew, Simon Peter's brother, said to Him,
(It was the Mary who poured the perfume over the Lord and wiped His feet with her hair, whose brother Lazarus was ill.)
and a considerable number of the Jews were with Martha and Mary, having come to express sympathy with them on the death of their brother.
So Martha came and spoke to Jesus. "Master, if you had been here," she said, "my brother would not have died.
Mary then, when she came to Jesus and saw Him, fell at His feet and exclaimed, "Master, if you had been here, my brother would not have died."
