Hymns of the Atharva Veda, by Ralph T.H. Griffith, [1895], at sacred-texts.com
1Whatever sacrifice that man performeth with voice, mind, sacred
    formula, oblation,
   May, in accord with Death, Destruction ruin his offering before
    it gain fulfilment.
 2For him may sorcerers, Destruction, demons strike and prevent
    fulfilment through their falsehood.
   Let Gods, by Indra sent, destroy his butter, and let his sacrifice
    be ineffective.
 3Let the two Sovrans, swift to come, like falcons swooping on
    their prey,
   Destroy the butter of the foe whoever plots to injure us.
 4I seize thine arms and draw them back, I bind a bandage on thy
    mouth.
   I with the anger of the God Agni have killed thy sacrifice. p. a300
 5Behind thy back I tie thine arms, I bind a bandage on thy
    mouth:
   With the terrific Agni's wrath have I destroyed thy sacrifice.
