'Sister' in the Bible

Now a certain man named Lazarus was ill; he was of Bethany, the town of Mary and her sister Martha.

Now Jesus had love in his heart for Martha and her sister and Lazarus.

And having said this, she went away and said secretly to her sister Mary, The Master is here and has sent for you.

Jesus said, Take away the stone. Martha, the sister of him who was dead, said, Lord, by this time the body will be smelling, for he has been dead four days.

Now by the side of the cross of Jesus were his mother, and his mother's sister Mary, the wife of Cleopas, and Mary Magdalene.
