Atharvaveda 5.11.11

5.11.11

devó devā́ya gr̥ṇaté vayodhā́ vípro víprāya stuvaté sumedhā́ḥ |
ájījano hí varuṇa svadhāvann átharvāṇaṃ pitáraṃ devábandhum |
tásmā u rā́dhaḥ kr̥ṇuhi supraśastáṃ sákhā no asi paramáṃ ca bándhuḥ ||11||

A god, bestower of vigor on a singing god; a sage (vípra), of good wisdom for a praising sage.
Since thou, O self-ruling Varuṇa, hast generated father Atharvan, connection of the gods, for him do thou make well-extolled generosity; our comrade art thou, and highest connection.
