'Unable' in the Bible

Who makes the designs of the wise go wrong, so that they are unable to give effect to their purposes.

He does not get wealth for himself, and is unable to keep what he has got; the heads of his grain are not bent down to the earth.

Your light is made dark so that you are unable to see, and you are covered by a mass of waters.

Thick clouds are covering him, so that he is unable to see; and he is walking on the arch of heaven.

And he was angry with his three friends, because they had been unable to give him an answer, and had not made Job's sin clear.

For I am full of words, I am unable to keep in my breath any longer:

My stomach is like wine which is unable to get out; like skins full of new wine, it is almost burst.

Make clear to me what we are to say to him; we are unable to put our cause before him, because of the dark.
