'Seven' in the Bible

Then the sons of Israel did what was evil in the sight of the Lord; and the Lord gave them into the hands of Midian seven years.

Now on the same night the Lord said to him, “Take your father’s bull and a second bull seven years old, and pull down the altar of Baal which belongs to your father, and cut down the Asherah that is beside it;

He had thirty sons, and thirty daughters whom he gave in marriage outside the family, and he brought in thirty daughters from outside for his sons. And he judged Israel seven years.

Then Samson said to them, “Let me now propound a riddle to you; if you will indeed tell it to me within the seven days of the feast, and find it out, then I will give you thirty linen wraps and thirty changes of clothes.

However she wept before him seven days while their feast lasted. And on the seventh day he told her because she pressed him so hard. She then told the riddle to the sons of her people.

Samson said to her, “If they bind me with seven fresh cords that have not been dried, then I will become weak and be like any other man.”

Then the lords of the Philistines brought up to her seven fresh cords that had not been dried, and she bound him with them.

Then Delilah said to Samson, “Up to now you have deceived me and told me lies; tell me how you may be bound.” And he said to her, “If you weave the seven locks of my hair with the web [and fasten it with a pin, then I will become weak and be like any other man.”

So while he slept, Delilah took the seven locks of his hair and wove them into the web]. And she fastened it with the pin and said to him, “The Philistines are upon you, Samson!” But he awoke from his sleep and pulled out the pin of the loom and the web.

She made him sleep on her knees, and called for a man and had him shave off the seven locks of his hair. Then she began to afflict him, and his strength left him.
