Romans 11:7-10,32

In the Old Testament, David prayed to God that the food of those who did not believe in God would become their snare and that their eyes would be blinded so that they could not see. (Psalms 69:22-23)

Psalms 69:22 Let their table become a snare before them: and that which should have been for their welfare, let it become a trap. 23 Let their eyes be darkened, that they see not; and make their loins continually to shake.

Their food became a snare to the people of Israel, and the people of Israel were blinded and unable to see. In other words, they did not recognize Christ, the bread of life for the people of Israel. (Romans 11:7-10)

Romans 11:7 What then? Israel hath not obtained that which he seeketh for; but the election hath obtained it, and the rest were blinded. 8 (According as it is written, God hath given them the spirit of slumber, eyes that they should not see, and ears that they should not hear;) unto this day. 9 And David saith, Let their table be made a snare, and a trap, and a stumblingblock, and a recompence unto them: 10 Let their eyes be darkened, that they may not see, and bow down their back alway.
