Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 23

Sanskrit:

क्षमध्वं मम दौरात्म्यं साधवो दीनवत्सला: ।इत्युक्त्वाश्रुमुख: पादौ श्याल: स्वस्रोरथाग्रहीत् ॥ २३ ॥

ITRANS:

kṣamadhvaṁ mama daurātmyaṁsādhavo dīna-vatsalāḥity uktvāśru-mukhaḥ pādauśyālaḥ svasror athāgrahīt

Translation:

Kaṁsa begged, “My dear sister and brother-in-law, please be merciful to such a poor-hearted person as me, since both of you are saintly persons. Please excuse my atrocities.” Having said this, Kaṁsa fell at the feet of Vasudeva and Devakī, his eyes full of tears of regret.

Purport:

Although Kaṁsa had spoken very nicely on the subject of real knowledge, his past deeds were abominable and atrocious, and therefore he further begged forgiveness from his sister and brother-in-law by falling at their feet and admitting that he was a most sinful person.
