'Sister' in the Bible

Now a certain man was sick, Lazarus from Bethany, the village of Mary and her sister Martha.

(Now Jesus loved Martha and her sister and Lazarus.)

And [when she] had said this, she went and called her sister Mary privately, saying, "The Teacher is here and is calling for you."

Jesus said, "Take away the stone." Martha, the sister of the one who had died, said to him, "Lord, he is stinking already, because it has been four days."

Now his mother and the sister of his mother, Mary the [wife] of Clopas, and Mary Magdalene were standing near the cross of Jesus.
