Judges 15:18-19

18Then he became very thirsty, so he called to Adonai and said, “You have granted this great deliverance by the hand of Your servant. So now, will I die of thirst and fall into the hand of the uncircumcised?”

19But God split the hollow place that is in Lehi, and water came out of it. When he drank, he regained his strength and revived. Therefore he called it En-hakkore, which is in Lehi to this day.
