Judges 15:18-19

18He became very thirsty and called out to the Lord, “You have accomplished this great victory through your servant. Must I now die of thirst and fall into the hands of the uncircumcised?”

19So God split a hollow place in the ground at Lehi, and water came out of it. After Samson drank, his strength returned, and he revived. That is why he named it Hakkore Spring, which is still in Lehi today.
