A Prophesy Gone Wrong

"Now a day before Saul's coming, the Lord had revealed this to Samuel saying, 'About this time tomorrow I will send you a man from the land of Benjamin, and you shall anoint him to be prince over my people Israel; and he shall deliver my people from the hand of the Philistines. For I have regarded my people, because their cry has come to me'" (1 Samuel 9:15-16)

Really?

The conclusion to this book has the Israelite army routed, Saul committing suicide, and the Philistines occupying Israelite towns! (chapter 31)

Perhaps Jehovah needs to brush up on his prophesying skills.
