They are disappointed because they were confident; they come there and are confounded. Job 6

 6 Then Job answered:

² “O that my vexation were weighed,
    and all my calamity laid in the balances!
³ For then it would be heavier than the sand of the sea;
    therefore my words have been rash.
⁴ For the arrows of the Almighty are in me;
    my spirit drinks their poison;
    the terrors of God are arrayed against me.
⁵ Does the wild ass bray over its grass,
    or the ox low over its fodder?
⁶ Can that which is tasteless be eaten without salt,
    or is there any flavor in the juice of mallows?
⁷ My appetite refuses to touch them;
    they are like food that is loathsome to me.

⁸ “O that I might have my request,
    and that God would grant my desire;
⁹ that it would please God to crush me,
    that he would let loose his hand and cut me off!
¹⁰ This would be my consolation;
    I would even exult in unrelenting pain;
    for I have not denied the words of the Holy One.
¹¹ What is my strength, that I should wait?
    And what is my end, that I should be patient?
¹² Is my strength the strength of stones,
    or is my flesh bronze?
¹³ In truth I have no help in me,
    and any resource is driven from me.

¹⁴ “Those who withhold kindness from a friend
    forsake the fear of the Almighty.
¹⁵ My companions are treacherous like a torrent-bed,
    like freshets that pass away,
¹⁶ that run dark with ice,
    turbid with melting snow.
¹⁷ In time of heat they disappear;
    when it is hot, they vanish from their place.
¹⁸ The caravans turn aside from their course;
    they go up into the waste, and perish.
¹⁹ The caravans of Tema look,
    the travelers of Sheba hope.
²⁰ They are disappointed because they were confident;
    they come there and are confounded.
²¹ Such you have now become to me;
    you see my calamity, and are afraid.
²² Have I said, ‘Make me a gift’?
    Or, ‘From your wealth offer a bribe for me’?
²³ Or, ‘Save me from an opponent’s hand’?
    Or, ‘Ransom me from the hand of oppressors’?

²⁴ “Teach me, and I will be silent;
    make me understand how I have gone wrong.
²⁵ How forceful are honest words!
    But your reproof, what does it reprove?
²⁶ Do you think that you can reprove words,
    as if the speech of the desperate were wind?
²⁷ You would even cast lots over the orphan,
    and bargain over your friend.

²⁸ “But now, be pleased to look at me;
    for I will not lie to your face.
²⁹ Turn, I pray, let no wrong be done.
    Turn now, my vindication is at stake.
³⁰ Is there any wrong on my tongue?
    Cannot my taste discern calamity?
