Romans 11:5-10

And that is but one example of what God is doing in this age of fulfillment, for God’s grace empowers his chosen remnant. And since it is by God’s grace, it can’t be a matter of their good works; otherwise, it wouldn’t be a gift of grace, but earned by human effort. So then, Israel failed to achieve what it had strived for, but the divinely chosen remnant receives it by grace, while the rest were hardened and unable to receive the truth. Just as it is written: God granted them a spirit of deep slumber. He closed their eyes to the truth and prevented their ears from hearing up to this very day. And King David also prophesied this: May their table prove to be a snare and a trap to cause their ruin. Bring them the retribution they deserve. Blindfold their eyes and don’t let them see. Let them be stooped over continually.
