Quotation על עבודה זרה 7:2

"would swallow alive:" As it is written (Habakkuk 1:14) "And you make man like the fish of the sea" - just like the fish of the sea, each one that is bigger than his fellow swallows his fellow; so too people, were it not for the fear of the government, each one who is bigger than his fellow would swallow his fellow (Avodah Zarah 4a).
