exaggerated anguish

—If the team loses the championship game, there will be weeping and gnashing of teeth throughout the whole city.

While Jesus was traveling around, teaching and healing people, a Roman military leader came to him saying that his servant was paralyzed and in pain. Jesus offered to come heal the servant, but the centurion said, “Lord, I am not worthy to have you come under my roof. Instead, just say the word and my servant will be healed.” When Jesus heard his response, he told those with him,

“I tell you the truth, I have not found such faith in anyone in Israel! I tell you, many will come from the east and west to share the banquet with Abraham, Isaac, and Jacob in the kingdom of heaven, but the sons of the kingdom will be thrown out into the outer darkness, where there will be weeping and gnashing of teeth.” Then Jesus said to the centurion, “Go; just as you believed, it will be done for you.” And the servant was healed at that hour. (Matthew 8:10-13)

Jesus message was this: Many non-Jews will choose to follow him, becoming part of God’s kingdom and enjoying the spiritual inheritance of Abraham, Isaac, and Jacob in heaven. But many Jews, the descendants of Abraham, Isaac, and Jacob, will choose not to follow him and will suffer outside the kingdom, in hell.

Here, “gnashing of teeth” means that a person is grinding his teeth together in pain and despair.
