Judges 15:20 In-Context

18 By then he was very thirsty, and he called on the Lord, saying, "You have granted this great victory by the hand of your servant. Am I now to die of thirst, and fall into the hands of the uncircumcised?"
19 So God split open the hollow place that is at Lehi, and water came from it. When he drank, his spirit returned, and he revived. Therefore it was named En-hakkore, which is at Lehi to this day.
