Romans 11:7-10

This little inset in verses eight through ten is important to understand. Israel has zeal for God, but not according to knowledge. God has not cast away His people. He is still going to save them, but He lets us know why things are the way they are. He has given them over to being deceived; He has permitted it. This is why it says that God gave them a spirit of stupor. He permitted it even as He permitted Adam and Eve to be tested in the Garden.

These scriptures show that Israel's spiritual diet was what was misleading them. Their table had become a snare. A table is a symbol of where we eat. It is literally where we eat physical food, but spiritually, it is a symbol of that which is providing our mental and spiritual nourishment. What is he saying here? It was what they were feeding their mind that was so distracting them to the degree that they were not able to see the truth when it was presented to them.
