Srimad Bhagavatam Canto 10, Chapter 64, Text 33

SB 10.64.33

naham halahalam manye
 visam yasya pratikriya
brahma-svam hi visam proktam
 nasya pratividhir bhuvi
 
Translation: 
 
I do not consider halahala to be real poison, because it has an antidote. But a brahmana’s property, when stolen, can truly be called poison, for it has no antidote in this world.
 
Purport: 
 
One who takes a brahmana’s property, thinking to enjoy it, has actually taken the most deadly poison.
