'Sister' in the Bible

Now a certain man was sick, Lazarus of Bethany, of 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 away, and called Mary her sister secretly, saying, The Teacher is here, and calleth thee.

Jesus saith, Take ye away the stone. Martha, the sister of him that was dead, saith unto him, Lord, by this time the body decayeth; for he hath been dead four days.

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