1 Corinthians 5:8
Patriarchal Greek New Testament (1904) · Berean Standard Bible
ὥστε ἑορτάζωμεν μὴ ἐν ζύμῃ παλαιᾷ, μηδὲ ἐν ζύμῃ κακίας καὶ πονηρίας, ἀλλ᾽ ἐν ἀζύμοις εἰλικρινείας καὶ ἀληθείας.
Therefore let us keep the feast, not with the old bread, leavened with malice and wickedness, but with the unleavened bread of sincerity and of truth.
