English translation:

“This hymn, the bestower of riches, has been addressed by the sages, with their own mouths, to the (class of) divinities having birth (lit. to the divine or brilliant birth; e.g. Ṛbhus--Ṛbhu, Vibhu and Vāja were pious men, who through penance became divinities).”

Commentary by Sāyaṇa: Ṛgveda-bhāṣya

Devāya janmane: lit. to the divine or brilliant birth;

Janmane: jāyamānāya, being born, or having birth;

Devāya: deva-saṅghāya, a class of divinities, Ṛbhus who achieved deification: manuṣyāḥ santastapasā devatvam prāptāḥ. Ṛbhus were three sons of Sudhanvan, a descendant of Aṅgiras. Through their good work (svapas = su-apas), they became divine, exercised superhuman powers and became entitled to receive praise and adoration. They dwell in the solar sphere, identified with the rays of the sun
