'Brothers' in the Bible

Then His mother and His brothers arrived, and standing outside they sent word to Him and called for Him.

A crowd was sitting around Him, and they said to Him, “Look! Your mother and Your brothers are outside asking for You.”

And He replied, “Who are My mother and My brothers?”

Looking at those who were sitting in a circle around Him, He said, “Here are My mother and My brothers!

Jesus said, “I assure you and most solemnly say to you, there is no one who has given up a house or brothers or sisters or mother or father or children or farms, for My sake and for the gospel’s sake,

who will not receive a hundred times as much now in the present age—houses and brothers and sisters and mothers and children and farms—along with persecutions; and in the age to come, eternal life.

There were seven brothers; the first [one] took a wife, and died leaving no children.
