Judges 15:13-14

13“No, we won’t kill you,” they said to him, “but we will bind you fast and hand you over to them.” So they bound him with two new ropes and brought him up from the rock.

14When he arrived at Lehi, the Philistines shouted upon meeting him. But the Ruach Adonai came mightily upon him so that the ropes that were on his arms became like flax burned with fire and his bonds melted off his wrists.
