LXX Deut 31:20

εἰσάξω γὰρ αὐτοὺς εἰς τὴν γῆν τὴν ἀγαθὴν ἢν ὤμοσα πατράσιν αὐτῶν, δοῦναι αὐτοῖς γῆν ῥέουσαν γάλα καὶ μέλι· καὶ φάγονται καὶ ἐμπλησθέντες κορήσουσιν, καὶ ἐπιστραφήσονται ἐπὶ θεοὺς ἀλλοτρίους καὶ παροξυνοῦσίν με καὶ διασκεδάσουσιν τὴν διαθήκην μου.

When I have brought them into the land that I swore to give their fathers, a land flowing with milk and honey, they will eat their fill and prosper. Then they will turn to other gods and worship them, and they will reject Me and break My covenant.
