LXX Gen 38:14

κα ὶ περιελομένη τὰ ἱμάτια τῆς χηρεύσεως ἀφ’ ἑαυτῆς περιεβάλετο θερίστρῳ καὶ ἐκαλλωπίσατο, καὶ ἐκάθισεν πρὸς ταῖς πύλαις Αἰνάν, ἥ ἐστιν ἐν παρόδῳ Θαμνά. ἴδεν γὰρ ὅτι μέγας γέγονεν Σηλὼμ ὁ υἱὸς αὐτοῦ, αὐτὸς δὲ οὐκ ἒδωκεν αὐτὴν αὐτῷ γυναῖκα.

she removed her widow’s garments, covered her face with a veil to disguise herself, and sat at the entrance to Enaim, which is on the way to Timnah. For she saw that although Shelah had grown up, she had not been given to him as a wife.
