'Strength' in the Bible

And as you saw the feet and toes, partly of potter’s clay and partly of iron, it will be a divided kingdom; but there will be in it some of the durability and strength of iron, just as you saw the iron mixed with common clay.

So I was left alone and saw this great vision; yet no strength was left in me, for my normal appearance turned to a deathly pale, and I grew weak and faint [with fright].

And behold, one who resembled the sons of men touched my lips. Then I opened my mouth and spoke and said to him who was standing before me, “O my lord, because of the vision anguish has come upon me, and I have retained no strength.

For how can such a [weakened] servant of my lord talk with such [a being] as my lord? For now there remains no strength in me, nor has any breath been left in me.”

Then the king of the North (Syria) will come and build up siege ramps and capture a well-fortified city. The forces of the South will not stand their ground, not even the finest troops, for there will be no strength to stand [against the Syrian king].

He will be determined to come with the power of his entire kingdom, and propose equitable conditions and terms of peace, which he will put into effect [by making an agreement with the king of the South]. He will also give him his daughter (Cleopatra I), in an attempt to overthrow the kingdom, but it will not succeed or be to his advantage.
