LXX Gen 19:35

ἐπότισαν δὲ καὶ ἐν τῇ νυκτὶ ἐκείνῃ τὸν πατέρα αὐτῶν οἶνον, καὶ εἰσελθοῦσα ἡ νεωτέρα ἐκοιμήθη μετὰ τοῦ πατρὸς αὐτῆς· καὶ οὐκ ᾔδει ἐν τῷ κοιμηθῆναι αὐτὴν καὶ ἀναστῆναι.

So again that night they got their father drunk with wine, and the younger daughter went in and slept with him; he was not aware when she lay down or when she got up.
