In this podcast, Dennis, with the backing of our Greek New Testament Grammatical Commentary database, shows that Nestle-Aland μενοῦν is an illegitimate compound of μέν. It is not the original word in Luke and violates the absolute postpositive prohibition against the initial position.

Luke 11:28 [Byz μενοῦνγε]

αὐτὸς δὲ εἶπεν

Μενοῦν μακάριοι εἰσίν

οἱ ἀκούοντες τὸν λόγον τοῦ Θεοῦ

καὶ φυλάσσοντες.

Then he said

Blessed indeed are

those who hear the word of God

and keep it.
