'Mother's' in the Bible

You may not have sex connection with your mother's sister, for she is your mother's near relation.

And you may not have sex connection with your mother's sister or your father's sister, for they are his near relations: their sin will be on them.

And the son of the Israelite woman said evil against the holy Name, with curses; and they took him to Moses. His mother's name was Shelomith, the daughter of Dibri, of the tribe of Dan.
