'Power' in the Bible

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

wherein 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 would assault them, their little ones and women, and to take the spoil of them for a prey,

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