'Strengthened' in the Bible

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

And he said, O man greatly beloved, fear not: peace be unto thee, be strong, yea, be strong. And when he spake unto me, I was strengthened, and said, Let my lord speak; for thou hast strengthened me.

And at the end of years they shall join themselves together; and the daughter of the king of the south shall come to the king of the north to make an agreement: but she shall not retain the strength of her 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 those times.
