'Retain' in the Bible

And I myself, Daniel, alone saw this great vision, and [as a result] {no strength was left in me} and {my complexion grew deathly pale}, and I did not retain any strength.

And behold, one after the likeness of the sons of men touched my lips; and I opened my mouth and spoke, and said unto him that stood before me, My lord, by reason of the vision my pains are turned upon me, and I retain no strength.

And in the end of years they shall join themselves together; for the king's daughter of the south shall come to the king of the north to make an agreement: but she shall not retain the power of the arm; neither shall he stand, nor his arm: but she shall be given up, and they that brought her, and he that begat her, and he that strengthened her in these times.
