'Power' in the Bible

Now these are thy servants and thy people, whom thou hast redeemed by thy great power, and by thy strong hand.

Yet now our flesh is as the flesh of our brethren, our children as their children: and, lo, we bring into bondage our sons and our daughters to be servants, and some of our daughters are brought into bondage already : neither is it in our power to help it; for other men have our fields and our vineyards.

And it yieldeth much increase unto the kings whom thou hast set over us because of our sins: also they have power over our bodies, and over our cattle, at their pleasure, and we are in great distress.
