Atharvaveda 7.27

7.27.1

íḍaivā́smā́m̐ ánu vastāṃ vraténa yásyāḥ padé punáte devayántaḥ |
ghr̥tápadī śákvarī sómapr̥ṣṭhópa yajñám asthita vaiśvadevī́ ||1||

Let Iḍā herself dress us with the vow (vratá), [she] in whose place {padá) the pious purify themselves; ghee-footed, able, soma-backed, she, belonging to all the gods, hath approached the offering.
