And his mother and his brothers arrived, and standing outside, they sent [word] to him to summon him.

And a crowd was sitting around him, and they told him, "Behold, your mother and your brothers [are] outside looking for you."

And he answered them [and] said, "Who is my mother or my brothers?"

And looking around at those who were sitting around him in a circle, he said, "Behold, my mother and my brothers!

Jesus said, "Truly I say to you, there is no one who has left house or brothers or sisters or mother or father or children or fields on account of me and on account of the gospel

{who will not} receive a hundred times as much now in this time--houses and brothers and sisters and mothers and children and fields, together with persecutions--and in the age to come, eternal life.

There were seven brothers, and the first took a wife. And [when he] died, he did not leave descendants.
