Can hendiadys ever have singular agreement?

Found one!

1 Corinthians 15:50

Τοῦτο δέ φημι, ἀδελφοί, ὅτι σὰρξ καὶ αἷμα βασιλείαν Θεοῦ κληρονομῆσαι οὐ δύναται, οὐδὲ ἡ φθορὰ τὴν ἀφθαρσίαν κληρονομεῖ.

“Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.”

The verb for cannot is singular in the Greek.

See also On Hendiadys in Greek. Nothing useful there, though it does mention that hendiadys is routinely ignored in accounts of Classical Greek—but noted in accounts of Biblical Greek.
