Judges 15:13-14

13They said, ‘We agree. We will only tie you up and give you to them. We promise that we will not kill you.’ So they tied him up with two new ropes. They took him with them away from the cave.

14When they arrived at Lehi, the Philistine soldiers shouted happily as they came towards him. But the Lord's Spirit gave Samson great strength. The ropes that tied his arms broke in pieces. They seemed as weak as grass that burns in a fire. They fell from his hands.
