'Unable' in the Bible

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

The wicked borrows and does not pay back,But the righteous is gracious and kind and gives.

For troubles without number have surrounded me;my sins have overtaken me; I am unable to see.They are more than the hairs of my head,and my courage leaves me.

You caused my acquaintances to shun me; you make me extremely abhorrent to them. Restrained, I am unable to go out.

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

This extraordinary knowledge is beyond me.It is lofty; I am unable to reach it.
