Romans 11:10 in the King James Version
Let their eyes be darkened, that they may not see, and bow down their back alway.
Context
9 David says, “Let their table be made a snare, a trap, a stumbling block, and a retribution to them.
10 Let their eyes be darkened, that they may not see. Always keep their backs bent.”
11 I ask then, did they stumble that they might fall? May it never be! But by their fall salvation has come to the Gentiles, to provoke them to jealousy.
