Okay kiddo, so Judges 15 is a story in the Bible about a man named Samson who was really strong. One day, Samson got married to a woman from a different tribe and when he came to visit her, he brought her dad a gift. But her dad thought that Samson didn't really like his daughter and gave her to someone else. Samson was very upset and wanted revenge.
So he caught a bunch of foxes and tied them together, then put torches on their tails and sent them into the fields of the people who took his wife. Their crops were destroyed by the fire and they were very angry. They went to the dad's house with a big group of men and took Samson's wife and her dad and burned them.
Samson was very angry and fought the men with the jawbone of a donkey. He killed a lot of them and then went to hide in a cave. But the Philistines, the people he was fighting against, went to find him and a big battle happened. Samson prayed to God for strength and was able to kill many of them.
In the end, Samson was very tired and thirsty and prayed to God for water. God listened and made water come out of a rock for him to drink. And that's what happened in Judges 15.
