Atharvaveda Samhita — Kanda 19 — Chapter 68
AV 19 68.1
अव्यसश् च व्यचसश् च बिलं वि ष्यामि मायया । ताभ्याम् उद्धृत्य वेदम् अथ कर्माणि कृण्महे
avyasaś ca vyacasaś ca bilaṃ vi ṣyāmi māyayā | tābhyām uddhṛtya vedam atha karmāṇi kṛṇmahe
Of the unextended and of the extended I open the aperture by (my) magic art; having drawn up the Veda from those two, we then perform the rites.

Compare with Ralph T.H. Griffith
Both of broad and narrow I with magic power unclose the mouth. With these when we have raised the bunch of grass we pay the holy rites.
— tr. Ralph T.H. Griffith (1895–96)
