Atharva Veda 2.35

ye bhakṣayanto na vasūny ānṛdhur yān agnayo anvatapyanta dhiṣṇyāḥ yā teṣām avayā duriṣṭiḥ sviṣṭiṃ nas tāṃ kṛṇavad viśvakarmā

To expiate errors in the sacrifice: to Viçvakarman

They who, partaking [of soma] (bhakṣ), did not prosper (ṛdh) in good things, whom the fires of the sacrificial hearth were distressed about (anu-tapya-)—what was the expiation (avayá) of their ill-sacrifice, may Viçvakarman ('the all-worker') make that for us a good sacrifice.

yajñapatim ṛṣayaḥ enasāhur nirbhaktaṃ prajā anutapyamānam mathavyānt stokān apa yān rarādha saṃ naṣ ṭebhiḥ sṛjatu viśvakarmā

The seers declare the master (-páti) of the sacrifice by reason of sin disportioned, distressed about [his] offspring. What honeyed drops he offended in (? apa-rādh), with them let Viçvakarman unite (sam-sṛj) us.

adānyānt somapān manyamāno yajñasya vidvānt samaye na dhīraḥ yad enaś cakṛvān baddha eṣa taṃ viśvakarman pra muñcā svastaye

Thinking the soma-drinkers to be unworthy of gifts (? adānyá), [though] knowing of the sacrifice, [he is] not wise (dhī́ra) in the conjuncture (samayá); in that this man is bound having committed a sin, do thou, O Viçvakarman, release him for his well-being.

ghorā ṛṣayo namo astv ebhyaś cakṣur yad eṣāṃ manasaś ca satyam bṛhaspataye mahiṣa dyuman namo viśvakarman namas te pāhy asmān

Terrible [are] the seers; homage be to them! what sight [is] theirs, and the actuality (satyá) of their mind. For Brihaspati, O bull (mahiṣá), [be] bright (dyumánt) homage; O Viçvakarman, homage to thee! protect thou us.

yajñasya cakṣuḥ prabhṛtir mukhaṃ ca vācā śrotreṇa manasā juhomi imaṃ yajñaṃ vitataṃ viśvakarmaṇā devā yantu sumanasyamānāḥ

The sacrifice's eye, commencement, and face: with voice, hearing, mind I make oblation. To this sacrifice, extended by Viçvakarman, let the gods come, well-willing.
