'Power' in the Bible

in the third year of his reign, he made a feast to all his princes and his servants; the power of Persia and Media, the nobles and the princes of the provinces being before him;

stating that the king granted the Jews that were in every city to gather themselves together, and to stand for their life, to destroy, to slay, and to cause to perish, all the power of the people and province that might assault them, their little ones and women, and to take the spoil of them for a prey,

And in the twelfth month, that is, the month Adar, on the thirteenth day thereof, when the king's commandment and his decree drew near to be put in execution, in the day that the enemies of the Jews hoped to have power over them (but it was turned to the contrary, that the Jews had power over them that hated them),

And all the acts of his power and of his might, and the declaration of the greatness of Mordecai, to which the king advanced him, are they not written in the book of the chronicles of the kings of Media and Persia?
