'Able' in the Bible

Everything is wearisome, more than man is able to express. The eye is never satisfied by seeing, nor the ear by hearing.

A crooked thing one is not able to make straight, and a lacking thing is not able to be numbered.

Whatever exists was given its name long ago, and it is known what man is. But he is not able to contend with the One stronger than he.

Who is able to say what is good for man in life all the days of his foolish life which he goes through like a shade? who will say what is to be after him under the sun?

Consider the work of God: Who is able to straighten what he has bent?

Since a king's command is powerful, who is able to challenge him, asking, "What are you doing?"

No one is certain what is to be, and who is able to say to him when it will be?

Then I beheld all the work of God, that a man cannot find out the work that is done under the sun: because though a man labour to seek it out, yet he shall not find it; yea further; though a wise man think to know it, yet shall he not be able to find it.

The foolish are full of words; man has no knowledge of what will be; and who is able to say what will be after him?
