'Strengthened' in the Bible

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

He said, "Greatly beloved man, don't be afraid: peace be to you, be strong, yes, be strong." When he spoke to me, I was strengthened, and said, "Let my lord speak; for you have strengthened me."

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 those who brought her, and he who became the father of her, and he who strengthened her in those times.
