'Sister' in the Bible

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

Now Jesus loved Martha, her sister, and Lazarus.

Having said this, she went back and called her sister Mary, saying in private, “The Teacher is here and is calling for you.”

“Remove the stone,” Jesus said.Martha, the dead man’s sister, told Him, “Lord, he’s already decaying. It’s been four days.”

Standing by the cross of Jesus were His mother, His mother’s sister, Mary the wife of Clopas, and Mary Magdalene.
