Judges 15:14

And when he came unto Lehi, where the headquarters of the enemy were, the Philistines shouted against him, their jubilant shouts met him, for they believed that he was now in their power. And the Spirit of the Lord came mightily upon him, filled him with invincible, superhuman strength, and the cords that were upon his arms became as flax that was burned with fire, like tow singed by the action of the flame. and his bands loosed from off his hands. literally, "melted or flowed from his hands," as though turned to a liquid.
