Judges 15:18-19

18And he was very thirsty, and he called upon the Lord and said, "You have granted this great salvation by the hand of your servant, and shall I now die of thirst and fall into the hands of the uncircumcised?"

19And God split open the hollow place that is at Lehi, and water came out from it. And when he drank, his spirit returned, and he revived. Therefore the name of it was called En-hakkore; it is at Lehi to this day.
