Parallel
Matthew 23:28
Patriarchal Greek New Testament (1904) · Berean Standard Bible
οὕτω καὶ ὑμεῖς ἔξωθεν μὲν φαίνεσθε τοῖς ἀνθρώποις δίκαιοι, ἔσωθεν δὲ μεστοί ἐστε ὑποκρίσεως καὶ ἀνομίας.
In the same way, on the outside you appear to be righteous, but on the inside you are full of hypocrisy and wickedness.
