Altaschith, Michtam of David.

Do ye indeed speak righteousness, O congregation ?
do ye judge uprightly, O ye sons of men?
² Yea, in heart ye work wickedness;
ye weigh the violence of your hands in the earth.

³ The wicked are estranged from the womb:
they go astray as soon as they be born,
speaking lies.
⁴ Their poison is like the poison of a serpent:
they are like the deaf adder that stoppeth her ear;
⁵ Which will not hearken to the voice of charmers, charming never so wisely
[whisperers, charming charms wisely].

⁶ Break their teeth, O God, in their mouth:
break out the great teeth of the young lions, O LORD.

⁷ Let them melt away
as waters which run continually:
when he bendeth his bow to shoot his arrows,
let them be as cut in pieces.
⁸ As a snail which melteth,
let every one of them pass away:
like the untimely birth of a woman,
that they may not see the sun.
⁹ Before your pots can feel the thorns,
he shall take them away as with a whirlwind,
both living, and in his wrath.

¹⁰ The righteous shall rejoice when he seeth the vengeance:
he shall wash his feet in the blood of the wicked.
¹¹ So that a man shall say,
Verily there is a reward for the righteous:
verily he is a God that judgeth in the earth.

* NOTE: On Opening and Closing Comments in the Psalms.
[Some commentators take the Psalm in Habakkuk 3 to be a standard model for the Psalms.
Habakkuk's Psalm begins with the name of the composer (Habakkuk) and a musical notation ("upon Shigionoth").
It closes with a dedication or a "send to" notice ("To the chief singer on my stringed instruments").
I have arranged similar material, where it is found in the Psalter, in accord with the model in Habakkuk.]
