'Unable' in the Bible

I can see the evildoers! They have fallen! They have been knocked down and are unable to get up!

For innumerable dangers surround me. My sins overtake me so I am unable to see; they outnumber the hairs of my head so my strength fails me.

My heart is parched and withered like grass, for I am unable to eat food.

Your knowledge is beyond my comprehension; it is so far beyond me, I am unable to fathom it.
