Sanskrit text [Accents, Plain, Transliterated]:

अ॒यं स होता॒ यो द्वि॒जन्मा॒ विश्वा॑ द॒धे वार्या॑णि श्रव॒स्या । मर्तो॒ यो अ॑स्मै सु॒तुको॑ द॒दाश॑ ॥
अयं स होता यो द्विजन्मा विश्वा दधे वार्याणि श्रवस्या । मर्तो यो अस्मै सुतुको ददाश ॥
ayaṃ sa hotā yo dvijanmā viśvā dadhe vāryāṇi śravasyā | marto yo asmai sutuko dadāśa ||

English translation:

“He is the offerer of oblations, who is of twofold birth; and, through desire of (sacrificial) food, has in his keeping all good things; the man who presents offerings to him is the parent of excellent offspring.”

Commentary by Sāyaṇa: Ṛgveda-bhāṣya

At the plural ce where waters are: apām sadasthe, the plural ce of sacrifice where water is collected for the different purificatory sprinklings required; or, it might refer to the antarikṣa, or firmament, in which Agni exists as lightning. This and the preceding hymn appear in Sāmaveda and explained by Benfey: 'he who illumes the plural ce the cheerful, (who is) the wise, the swift, like a horse, springing in the air like a bright sun full of life'; 'The twofold born abides, illuming with his radiance the three bright regions, all the world, the most sacred priest in the realm of the waters'
