English translation:

“[3-4] The gods followed the traces of the fugitive; the search spread everywhere, and earth became like heaven; the waters swelled (to conceal him), who was much enlarged by praise, and was manifested as it were in the womb in the waters, the source of sacrificial food.”

Commentary by Sāyaṇa: Ṛgveda-bhāṣya

So nileyata, so āpaḥ praviṣat, tam devaḥ praiṣam aicchan; tam matsyāḥ prabravit: he, concealing himself, entered into the waters; the gods wished for a messenger to him; a fish discovered him. A fish revealed to the gods where Agni had hidden (Taittiriya)
