'Sister' in the Bible

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

Now Jesus loved Martha, and her sister, and Lazarus.

When she had said this, she went away, and called Mary, her sister, secretly, saying, "The Teacher is here, and is calling you."

Jesus said, "Take away the stone." Martha, the sister of him who was dead, said to him, "Lord, by this time there is a stench, for he has been dead four days."

But there were standing by the cross of Jesus his mother, and his mother's sister, Mary the wife of Clopas, and Mary Magdalene.
