Atharva Veda 2.7

aghadviṣṭā devajātā vīrucchapathayopanī āpo malam iva prāṇaikṣīt sarvān macchapathāṁ adhi

Against curses and cursers: with a plant

Hated by mischief, god-born, the curse-effacing plant hath washed away from me all curses, as waters do filth.

yaś ca sāpatnaḥ śapatho jāmyāḥ śapathaś ca yaḥ brahmā yan manyutaḥ śapāt sarvaṃ tan no adhaspadam

Both the curse that is a rival's, and the curse that is a sister's, what a priest (? brahmán) from fury may curse—all that [be] underneath our feet.

From the sky [is] the root stretched down, from off the earth stretched up; with this, thousand-jointed (-kā́ṇḍa), do thou protect us about on all sides.

This verse is not included in this edition.

Protect me about, my progeny, [and] what riches are ours; let not the niggard get the better (tṛ) of us; let not hostile plotters get the better of us.

cakṣurmantrasya durhārdaḥ pṛṣṭīr api śṛṇīmasi

Let the curse go to the curser; our [part] is along with him that is friendly (suhā́rd); of the eye-conjurer (-mántra), the unfriendly, we crush in the ribs (pṛṣṭí).
