Judges 15:13-14

13“No,” they answered, “we will not kill you, but we will tie you up securely and hand you over to them.” So they bound him with two new ropes and led him up from the rock.

14When Samson arrived in Lehi, the Philistines came out shouting against him. And the Spirit of the LORD came mightily upon him. The ropes on his arms became like burnt flax, and the bonds broke loose from his hands.
