This is a quotation from Śrīmad-Bhāgavatam (2.7.40). In the Ṛg Veda mantras (1.2.154.1), it is said:
oṁ viṣṇor nu vīryāṇi kaṁ prāvocaṁ
yaḥ pārthivāni vimame rajāṁsi
yo ’skambhayad uttaraṁ sadha-sthaṁ
vicakramāṇas tredhorugāyaḥ
The meaning of this verse is practically identical to that of the verse from Śrīmad-Bhāgavatam quoted above.
