Μὴ δῶτε τὸ ἅγιον τοῖς κυσί, μηδὲ βάλητε τοὺς μαργαρίτας ὑμῶν ἔμπροσθεν τῶν χοίρων · μήποτε καταπατήσωσιν αὐτοὺς ἐν τοῖς ποσὶν αὐτῶν, καὶ στραφέντες ῥήξωσιν ὑμᾶς.

Do not give what is holy to dogs, and do not cast your pearls before pigs, lest they trample them under their feet, then turn and rend you.
