'Power' in the Bible

Say thou, Thus saith the Lord GOD; Shall it prosper? shall he not pull up the roots thereof, and cut off the fruit thereof, that it wither? it shall wither in all the leaves of her spring, even without great power or many people to pluck it up by the roots thereof.

Behold, the princes of Israel, every one were in thee to their power to shed blood.

Thus saith the LORD; They also that uphold Egypt shall fall; and the pride of her power shall come down: from the tower of Syene shall they fall in it by the sword, saith the Lord GOD.
