'Brothers' in the Bible

Then his mother and his brothers arrived. Milling around outside, they sent for him, continuously summoning him.

A crowd was sitting around him. They told him, "Look! Your mother and your brothers are outside asking for you."

He answered them, "Who are my mother and my brothers?"

Then looking at the people sitting around him, he said, "Here are my mother and my brothers!

Jesus said, "I tell all of you with certainty, there is no one who has left his home, brothers, sisters, mother, father, children, or fields because of me and the gospel

who will not receive a hundred times as much here in this world homes, brothers, sisters, mothers, children, and fields, along with persecution as well as eternal life in the age to come.

There were seven brothers. The first one married and died without having children.
