A.T. Robertson Commentary 2 Corinthians 3:15

"But unto this day, whensoever Moses is read, a veil lieth upon their heart." — 2 Corinthians 3:15 (ASV)

Whensoever Moses is read (ηνικα αν αναγινωσκητα Μωυσης). Indefinite temporal clause with ηνικα an and the present passive subjunctive.

A veil lieth upon their heart (επ την καρδιαν αυτων κειτα). Vivid and distressing picture, a fact that caused Paul agony of heart (Romans 9:1–5). With wilful blindness the rabbis set aside the word of God by their tradition in the time of Jesus (Mr 7:8f.).
