LXX Deut 28:68

καὶ ἀποστρέψει σε κύριος εἰς Αἴγυπτον ἐν πλοίοις, ἐν τῇ ὁδῷ ᾗ εἶπα Οὐ προσθήσει ἔτι ἰδεῖν αὐτήν· καὶ πραθήσεσθε ἐκεῖ τοῖς ἐχθροῖς ὑμῶν εἰς παῖδας καὶ παιδίσκας, καὶ οὐκ ἔσται ὁ κτώμενος.

The LORD will return you to Egypt in ships by a route that I said you should never see again. There you will sell yourselves to your enemies as male and female slaves, but no one will buy you.”
