Fragment 4Q280 describes a series of curses laid upon Melchiresa:
“Accur]sed are you, Melki-resha, in all the pla[ns of your guilty inclination. May God [make you] an object of dread at the hand of those exacting vengeance. May God not favour you when you call on him. [May he lift his angry face] upon you for a curse. May there be no peace for you in the mouth of those who intercede. [Be cursed,] without a remnant; and be damned, without salvation.” – 4Q280
Melchiresa also appears in 11QMelch in direct opposition to Melchizedek, the leader of the forces of good.
