'Prayed' in the Bible

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.
