'Strength' in the Bible

“The torrent Kishon swept the enemy away,The ancient torrent, the torrent Kishon.O my soul, march on with strength.

Then Zebah and Zalmunna said, “Rise up yourself and strike us; for as the man is, so is his strength.” So Gideon arose and killed Zebah and Zalmunna, and took the crescent amulets that were on their camels’ necks.

So the [five] lords (governors) of the Philistines came to her and said to her, “Persuade him, and see where his great strength lies and [find out] how we may overpower him so that we may bind him to subdue him. And each of us will give you eleven hundred pieces of silver.”

So Delilah said to Samson, “Please tell me where your great strength lies and with what you may be bound and subdued.”

Now she had men lying in ambush in an inner room. And she said to him, “The Philistines are upon you, Samson!” And he broke the cords as a string of tow breaks when it touches fire. So [the secret of] his strength was not discovered.

Then she said to him, “How can you say, ‘I love you,’ when your heart is not with me? You have mocked me these three times and have not told me where your great strength lies.”

Then [finally] he told her everything that was in his heart and said to her, “A razor has never been used on my head, for I have been a Nazirite to God from my mother’s womb. If I am shaved, then my strength will leave me, and I will become weak and be like any [other] man.”

She made Samson sleep on her knees, and she called a man and had him shave off the seven braids of his head. Then she began to abuse Samson, and his strength left him.
