Matthew 6:24

Οὐδεὶς δύναται δυσὶ κυρίοις δουλεύειν· ἢ γὰρ τὸν ἕνα μισήσει, καὶ τὸν ἕτερον ἀγαπήσει· ἢ ἑνὸς ἀνθέξεται· καὶ τοῦ ἑτέρου καταφρονήσει· οὐ δύνασθε Θεῷ δουλεύειν καὶ μαμωνᾷ.

No one can serve two masters. For either he will hate the one, and love the other, or he will be devoted to the one, and despise the other. You cannot serve God and Mamona.

* Mamona, mammon, or money
