Judges 16:6-8

Lexham English Bible

⁶ So Delilah said to Samson, “Please tell me what makes your strength so great, and with what can you be tied up to subdue you?” ⁷ Samson said to her, “If you tie me up with seven fresh bowstrings that are not dried up, I will become weak like everyone else.” ⁸ So the rulers of the Philistines brought up to her seven fresh bowstrings that were not dried up, and she tied him up with them.
