Srimad-Bhagavatam: Canto 3 - Chapter 1 - Verse 24

Sanskrit:

ततो हसन् सभगवानसुरैर्निरपत्रपै: ।अन्वीयमानस्तरसा क्रुद्धो भीत: परापतत् ॥ २४ ॥

ITRANS:

tato hasan sa bhagavānasurair nirapatrapaiḥanvīyamānas tarasākruddho bhītaḥ parāpatat

Translation:

The worshipful Brahmā first laughed at their stupidity, but finding the shameless asuras close upon him, he grew indignant and ran in great haste out of fear.

Purport:

Sexually inclined demons have no respect even for their father, and the best policy for a saintly father like Brahmā is to leave such demoniac sons.
