'Sister' in the Bible

He is not to defile himself on account of his father, mother, brother, and sister when they die, because the crown of his consecration to God is on his head.

Now Kohath had a son named Amram. Amram's wife was Levi's daughter Jochebed, who was born to Levi in Egypt. She gave birth to Aaron, Moses, and their sister Miriam.
