'Strength' in the Bible

Yet it was I who destroyed the Amorites in front of them, though their height seemed like a cedar, though their strength seemed like an oak, but whose fruit I destroyed from above and the roots from beneath.

So the swift runner will not escape, the valiant will not fortify his strength, and the mighty warrior will not save his life.

You rejoice in nothing worth mentioning that is, you keep on saying, "We captured Karnaim by our own strength of will and by our own effort, didn't we?'
