Judges 15:13-14

13They said to him, “We promise! We will only take you prisoner and hand you over to them. We promise not to kill you.” They tied him up with two brand new ropes and led him up from the cliff.

14When he arrived in Lehi, the Philistines shouted as they approached him. But the Lord’s spirit empowered him. The ropes around his arms were like flax dissolving in fire, and they melted away from his hands.
