When he came to Lehi, the Philistines shouted as they met him: and the Spirit of Yahweh came mightily on him, and the ropes that were on his arms became as flax that was burnt with fire, and his bands dropped from off his hands.
Samson’s prayer, his first in the story, reveals that he knew he was participating in holy war as God’s deliverer (Judges 15:18). He gave God the credit for his victory. The word translated "thou" or "you" is in the emphatic position in the Hebrew text. He cried out to the Lord for water after his strenuous fight. God amazingly and graciously provided water for His rebellious servant in a very unusual way, and Samson’s strength revived (Judges 15:19; cf. Exodus 17:6; Numbers 20:11). Samson named that place "Supplicant’s Spring."
