Atharvaveda Samhita — Kanda 7 — Chapter 44
AV 7 44.1
उभा जिग्यथुर् न परा जयेथे न परा जिग्ये कतरश् चनैनयोः । इन्द्रश् च विष्णो यद् अपस्पृधेथां त्रेधा सहस्रं वि तद् ऐरयेथाम्
ubhā jigyathur na parā jayethe na parā jigye kataraś canainayoḥ | indraś ca viṣṇo yad apaspṛdhethāṃ tredhā sahasraṃ vi tad airayethām
You two have both conquered; you are not conquered away; neither one of these two was conquered away. Indra and Viṣṇu, when you two contended, you divided that thousand threefold.

Compare with Ralph T.H. Griffith
Ye twain have conquered, and have not been vanquished: not either of the pair hath been defeated. Ye, Indra Vishnu, when ye fought your battle; produced this infinite with three divisions.
— tr. Ralph T.H. Griffith (1895–96)
