Yes, I have encountered and unfortunately still encounter these people from time-to-time.
Psalm 57:6 King James Version
6 They have prepared a net for my steps; my soul is bowed down: they have digged a pit before me, into the midst whereof they are fallen themselves. Selah.
Psalm 56:5-7 New King James Version
5 All day they twist my words;
All their thoughts are against me for evil.
6 They gather together,
They hide, they mark my steps,
When they lie in wait for my life.
7 Shall they escape by iniquity?
In anger cast down the peoples, O God!
Psalm 91:7 King James Version
7 A thousand shall fall at thy side, and ten thousand at thy right hand; but it shall not come nigh thee.
Ping to above as well
Psalm 64:5-7 New King James Version
5 They encourage themselves in an evil matter;
They talk of laying snares secretly;
They say, “Who will see them?”
6 They devise iniquities:
“We have perfected a shrewd scheme.”
Both the inward thought and the heart of man are deep.
7 But God shall shoot at them with an arrow;
Suddenly they shall be wounded.
