Judges 15:13-14

13And they spoke to him, saying, No; but we will bind thee securely, and deliver thee into their hand: but surely we will not kill thee. And they bound him with two new cords, and brought him up from the rock. 14And when he came to Lehi, the Philistines shouted against him: and the Spirit of the LORD came mightily upon him, and the cords that were upon his arms became as flax that was burnt with fire, and his bands loosed from off his hands.1
