Judges 15:14-19

When he came to Lehi, the Philistines came shouting to meet him. And the Spirit of the LORD came upon him mightily, and the ropes on his arms were like flax (linen) that had been burned, and his bonds dropped off his hands. He found a fresh jawbone of a donkey, so he reached out his hand and took it and killed a thousand men with it. Then Samson said, “With the jawbone of a donkey, Heaps upon heaps, With the jawbone of a donkey I have struck down a thousand men.” When he finished speaking, he threw the jawbone from his hand; and he named that place Ramath-lehi (hill of the jawbone). Then Samson was very thirsty, and he called out to the LORD and said, “You have given this great victory through the hand of Your servant, and now am I to die of thirst and fall into the hands of the uncircumcised (pagans)?” So God split open the hollow place that was at Lehi, and water came out of it. When Samson drank, his spirit (strength) returned and he was revived. Therefore he named it En-hakkore (spring which is calling), which is at Lehi to this day.
