Srimad Bhagavatam Canto 08, Chapter 21, Text 10

SB 8.21.10

na vayam brahma-bandhur
 visnur mayavinam varah
dvija-rupa-praticchanno
 deva-karyam cikirsati
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
“This Vamana is certainly not a brahmana but the best of cheaters, Lord Visnu. Assuming the form of a brahmana, He has covered His own form, and thus He is working for the interests of the demigods.
