Numbers 26:59

and Amram's wife was called Jochebed; a daughter of Levi, which was born him in Egypt. And she bare unto Amram, Aaron, Moses and Miriam their sister.

And Amram took Jochebed his niece to wife which bare him Aaron and Moses. And Amram lived a hundred and thirty seven years.

And there went a man of the house of Levi and took a daughter of Levi.

Thou shalt not uncover the privities of thy father's sister, for she is thy father's next kin.
