Śrīmad-Bhāgavatam · Text 2.7.9
Who is speaking and story frame
यद्वेनमुत्पथगतं द्विजवाक्यवज्र-
निष्प्लुष्टपौरुषभगं निरये पतन्तम् ।
त्रात्वार्थितो जगति पुत्रपदं च लेभे
दुग्धा वसूनि वसुधा सकलानि येन ॥ ९ ॥
yad venam utpatha-gataṁ dvija-vākya-vajra-
niṣpluṣṭa-pauruṣa-bhagaṁ niraye patantam
trātvārthito jagati putra-padaṁ ca lebhe
dugdhā vasūni vasudhā sakalāni yena
Mahārāja Vena went astray from the path of righteousness, and the brāhmaṇas chastised him by the thunderbolt curse. By this King Vena was burnt with his good deeds and opulence and was en route to hell. The Lord, by His causeless mercy, descended as his son, by the name of Pṛthu, delivered the condemned King Vena from hell, and exploited the earth by drawing all kinds of crops as produce.
