Your question What event was Jesus predicting in Luke 17:22-37? Here are the verses you’re referring to. Let’s break it down verse by verse.

Christ is showing them that life will go on as normal right up to his coming. People will be eating and drinking, they’ll be in marriages and those given in marriage right up to the end. Then the destruction will come. I hope this has given you an understanding of wh
