'Able' in the Bible

I will smite them through, so that they shall not be able to rise: They shall fall under my feet.

For they intended evil against thee; They conceived a device which they are not able to perform.

There are the workers of iniquity fallen: They are thrust down, and shall not be able to rise.

For innumerable evils have compassed me about; Mine iniquities have overtaken me, so that I am not able to look up; They are more than the hairs of my head; And my heart hath failed me.
