3. Mose (Wajikra) 18:8

ערות אשת אביך THE NAKEDNESS OF THY FATHER'S WIFE [SHALT THOU NOT UNCOVER] — This is intended to include in the prohibition of union with one's father's wife already mentioned v. 7. even the doing of this after his death (Sanhedrin 54a).

KOREN

The nakedness of thy father’s wife shalt thou not uncover: it is thy father’s nakedness.
