They said to him.
And your sisters
Asking for you.’”
καὶ ἐκάθητο περὶ αὐτὸν ὄχλος, καὶ λέγουσιν αὐτῷ Ἰδοὺ ἡ μήτηρ σου καὶ οἱ ἀδελφοί σου καὶ αἱ ἀδελφαί σου ἔξω ζητοῦσίν σε.
Luke, chapter 8:20, and Matthew, chapter 12:47, have something similar, almost word for word, so that Mark might be the source of this saying. Mark indicated that someone from the crowd sitting around him (καὶ ἐκάθητο περὶ αὐτὸν ὄχλος) said that he should look (καὶ λέγουσιν αὐτῷ Ἰδοὺ) because his mother (ἡ μήτηρ σου), his brothers (καὶ οἱ ἀδελφοί σου), and his sisters (καὶ αἱ ἀδελφαί σου) were outside (ἔξω) wanting to talk to him or searching for him (ζητοῦσίν σε). Matthew and Luke never mentioned anything about his sisters, only his brothers, who were all unnamed.
