Romans 11:7-8

7So this is the situation: Most of the people of Israel have not found the favor of God they are looking for so earnestly. A few have—the ones God has chosen—but the hearts of the rest were hardened.

8As the Scriptures say, “God has put them into a deep sleep. To this day he has shut their eyes so they do not see, and closed their ears so they do not hear.”
