LXX Deut 13:16

καὶ πάντα τὰ σκῦλα αὐτῆς συνάξεις εἰς τὰς διόδους αὐτῆς, καὶ ἐνπρήσεις τὴν πόλιν ἐν πυρὶ καὶ πάντα τὰ σκῦλα αὐτῆς πανδημεὶ ἐναντίον Κυρίου τοῦ θεοῦ σου· καὶ ἔσται ἀοίκητος εἰς τὸν αἰῶνα, οὐκ ἀνοικοδομηθήσεται ἔτι.

And you are to gather all its plunder in the middle of the public square, and completely burn the city and all its plunder as a whole burnt offering to the LORD your God. The city must remain a mound of ruins forever, never to be rebuilt.
