Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 26-27

Sanskrit:

श्रीपरीक्षिदुवाचसंस्थापनाय धर्मस्य प्रशमायेतरस्य च ।अवतीर्णो हि भगवानंशेन जगदीश्वर: ॥ २६ ॥स कथं धर्मसेतूनां वक्ता कर्ताभिरक्षिता ।प्रतीपमाचरद् ब्रह्मन् परदाराभिमर्शनम् ॥ २७ ॥

ITRANS:

śrī-parīkṣid uvācasaṁsthāpanāya dharmasyapraśamāyetarasya caavatīrṇo hi bhagavānaṁśena jagad-īśvaraḥ

Translation:

Parīkṣit Mahārāja said: O brāhmaṇa, the Supreme Personality of Godhead, the Lord of the universe, has descended to this earth along with His plenary portion to destroy irreligion and reestablish religious principles. Indeed, He is the original speaker, follower and guardian of moral laws. How, then, could He have violated them by touching other men’s wives?

Purport:

As Śukadeva Gosvāmī was speaking, King Parīkṣit noticed that some persons seated in the assembly on the bank of the Ganges were harboring doubt about the Lord’s activities. These doubtful persons were karmīs, jñānīs and others who were not devotees of the Lord. To clear up their doubts, King Parīkṣit asks this question on their behalf.
