Imprecatory prayers are found in Psalms, 69 and 109 are most known for their imprecatory material, but several other psalms contain these “judgment prayers” as well.
For example, in Psalm 69:28 David prays this regarding his persecutors, “Let them be blotted out of the book of the living; let them not be enrolled among the righteous.” It seems David not only prays for their death, but possibly that they would be eternally lost as well.
Psalm109
Hold not thy peace, O God of my praise;
2 for the mouth of the wicked and the mouth of the deceitful are opened against me:
they have spoken against me with a lying tongue.
3 They compassed me about also with words of hatred;
and fought against me without a cause.
4 For my love they are my adversaries:
but I give myself unto prayer.
5 And they have rewarded me evil for good,
and hatred for my love. and let Satan stand at his right hand.
7 When he shall be judged, let him be condemned:
and let his prayer become sin.
8 Let his days be few;
and let another take his office.
9 Let his children be fatherless, and his wife a widow.
10 Let his children be continually vagabonds, and beg: let them seek their bread also out of their desolate places.
11Let the extortioner catch all that he hath;
and let the strangers spoil his labor.
12Let there be none to extend mercy unto him:
neither let there be any to favor his fatherless children.
13Let his posterity be cut off;
and in the generation following let their name be blotted out.
14 Let the iniquity of his fathers be remembered with the LORD;
and let not the sin of his mother be blotted out.
15 Let them be before the LORD continually,
that he may cut off the memory of them from the earth.
16 Because that he remembered not to show mercy,
but persecuted the poor and needy man, that he might even slay the broken in heart.
17 As he loved cursing,
so let it come unto him:
as he delighted not in blessing,
so let it be far from him.
18 As he clothed himself with cursing like as with his garment,
so let it come into his bowels like water,
and like oil into his bones.
19 Let it be unto him as the garment which covereth him,
and for a girdle wherewith he is girded continually.
20 Let this be the reward of mine adversaries from the LORD,
and of them that speak evil against my soul.
