Judges 16:7-9

7Samson told her, “If someone ties me up with seven new bowstrings that are not dried out, I will be like any other man.”

8The Philistine rulers brought her seven new bowstrings that were not dried out. She tied Samson up with them.

9Some men were hiding in the bedroom waiting for her ⌞to tie him up⌟. Then she said to him, “Samson, the Philistines are attacking!” Samson snapped the bowstrings as a thread snaps when it touches fire. So no one found out why he was so strong.
