{It shall turn} (epistrepsei). The heart of Israel. {The
veil is taken away} (periaireitai to kalumma). Present passive
indicative of periaire(935c), old verb, to take from around, as of
anchors ( Ac 27:40 ), to cut loose ( Ac 28:13 ), for hope to be
taken away ( Ac 27:20 ). Here Paul has in mind  Ex 34:34  where
we find of Moses that peri(8869)reito to kalumma (the veil was
taken from around his face) whenever he went before the Lord.
After the ceremony the veil is taken from around (peri-) the
face of the bride.
