'Strengthened' in the Bible

Then there touched me again one like the appearance of a man, and he strengthened me;

and he said, Fear not, man greatly beloved; peace be unto thee, be strong, yea, be strong. And as he was speaking with me I was strengthened, and I said, Let my lord speak; for thou hast strengthened me.

And after the course of years they shall join affinity; and the king's daughter of the south shall come to the king of the north to make equitable conditions: but she shall not retain the strength of her arm; neither shall he stand, nor his arm; and she shall be given up, she and they that brought her, and he that begat her, and he that strengthened her in those times.
