“Thus,

They do not honor

Their father

Or their mother

For the sake

Of their tradition.

You have made void

The word of God.

You hypocrites!

Isaiah prophesied of you,

When he said.”

οὐ μὴ τιμήσει τὸν πατέρα αὐτοῦ ἢ τὴν μητέρα αὐτοῦ· καὶ ἠκυρώσατε τὸν λόγον τοῦ Θεοῦ διὰ τὴν παράδοσιν ὑμῶν.

ὑποκριταί, καλῶς ἐπροφήτευσεν περὶ ὑμῶν Ἡσαΐας λέγων

There is something similar to this in Mark, chapter 7:6.  Jesus pointed out that for the sake of their traditions (διὰ τὴν παράδοσιν ὑμῶν), they did not honor their father or their mother (οὐ μὴ τιμήσει τὸν πατέρα αὐτοῦ ἢ τὴν μητέρα αὐτοῦ).  They have made void or cancelled out the word of God (καὶ ἠκυρώσατε τὸν λόγον τοῦ Θεοῦ).  These Pharisees were the kind of hypocrites that Isaiah, chapter 29:3, had prophesied about (ὑποκριταί, καλῶς ἐπροφήτευσεν περὶ ὑμῶν Ἡσαΐας λέγων).  This was a favorite term of Matthew for these Pharisees, hypocrites, people who play a part in a drama, but who are not sincere.
