7 O Lord, you have deceived me,
and I was deceived;
you are stronger than I,
and you have prevailed.
I have become a laughingstock all the day;
everyone mocks me.
8 For whenever I speak, I cry out,
I shout, “Violence and destruction!”
For the word of the Lord has become for me
a reproach and derision all day long.
9 If I say, “I will not mention him,
or speak any more in his name,”
there is in my heart as it were a burning fire
shut up in my bones,
and I am weary with holding it in,
and I cannot.
10 For I hear many whispering.
Terror is on every side!
“Denounce him! Let us denounce him!”
say all my close friends,
watching for my fall.
“Perhaps he will be deceived;
then we can overcome him
and take our revenge on him.”
11 But the Lord is with me as a dread warrior;
therefore my persecutors will stumble;
they will not overcome me.
They will be greatly shamed,
for they will not succeed.
Their eternal dishonor
will never be forgotten.
12 O Lord of hosts, who tests the righteous,
who sees the heart and the mind, 
let me see your vengeance upon them,
for to you have I committed my cause.
13 Sing to the Lord;
praise the Lord!
For he has delivered the life of the needy
from the hand of evildoers. (ESV)
