Atharvaveda Samhita — Kanda 19 — Chapter 25
AV 19 25.1
अश्रान्तस्य त्वा मनसा युनज्मि प्रथमस्य च । उत्कूलम् उद्वहो भवोदुह्य प्रति धावतात्
aśrāntasya tvā manasā yunajmi prathamasya ca | utkūlam udvaho bhavoduhya prati dhāvatāt
With the mind of the untiring one, and of the first one, I yoke thee. Be one who draws uphill; having drawn up, run back again.

Compare with Ralph T.H. Griffith
I yoke thee with the mind of one unwearied still and first of all. Be thou a bearer up the hill: run hither bearing up thy load.
— tr. Ralph T.H. Griffith (1895–96)
