Theophylact of Ohrid, on Rom 11:25

“For I would not have you ignorant, brethren, of this mystery, (lest you should be wise in your own conceits), that blindness in part has happened in Israel, until the fulness of the Gentiles should come in.”

“He calls a mystery here that which is unknown and hidden. What then does this mystery consist of? In that the Jews did not all disbelieve, but were hardened in part. Many of them believed, whom, as was said above, God foreknew, and many will believe afterward; for the Israelites were hardened until all the Gentiles foreknown by God are saved.”
