Judges 15:18-19

18Samson was now very thirsty. He called out to the Lord for help. He said, ‘You have helped me to win a great battle. Should I now die because I am so thirsty? Then these Philistines would do whatever they want to me.’

19So God caused a hole to open in the ground near Lehi. Water poured out of it. Samson drank some water and he became strong again. Samson called the spring of water ‘En Hakkore’. It is still there in Lehi.
