LXX Deut 12:30

πρόσεχε σεαυτῷ μὴ ἐκζητήσῃς ἐπακολουθῆσαι αὐτοῖς μετὰ τὸ ἐξολεθρευθῆναι αὐτοὺς ἀπὸ προσώπου σου, λέγων Ἠὼς ποιοῦσιν τὰ ἔθνη ταῦτα τοῖς θεοῖς αὐτῶν; ποιήσω κἀγώ.

be careful not to be ensnared by their ways after they have been destroyed before you. Do not inquire about their gods, asking, “How do these nations serve their gods? I will do likewise.”
