Do not keep silent,
O God of my praise!
For the mouth of the wicked and the mouth of the deceitful
Have opened against me;
They have spoken against me with a lying tongue.
They have also surrounded me with words of hatred,
And fought against me without a cause.
In return for my love they are my accusers,
But I give myself to prayer.
Thus they have rewarded me evil for good,
And hatred for my love.
Set a wicked man over him,
And let an accuser stand at his right hand.
When he is judged, let him be found guilty,
And let his prayer become sin.
Ps 110:1-7
(NKJV)
