Judges 16:5

3And Samson lay till midnight, and arose at midnight, and took the doors of the gate of the city, and the two posts, and went away with them, bar and all, and put them upon his shoulders, and carried them up to the top of an hill that is before Hebron.

4And it came to pass afterward, that he loved a woman in the valley of Sorek, whose name was Delilah.

5And the lords of the Philistines came up unto her, and said unto her, Entice him, and see wherein his great strength lieth, and by what means we may prevail against him, that we may bind him to afflict him; and we will give thee every one of us eleven hundred pieces of silver.

6And Delilah said to Samson, Tell me, I pray thee, wherein thy great strength lieth, and wherewith thou mightest be bound to afflict thee.

7And Samson said unto her, If they bind me with seven green withs that were never dried, then shall I be weak, and be as another man.
