“No animal must ever live in a house, or sleep in a bed, or wear clothes, or drink alcohol”
Context: Old Major warns the animals never to adopt the habits of Man, which he sees as inherently corrupt.
Analysis
The listing of forbidden human behaviours establishes a strict moral code that the pigs will systematically break, each violation marking another stage of corruption. The modal "must ever" makes the rule sound absolute and permanent — yet it is precisely these commandments that Squealer quietly amends. Orwell foreshadows the betrayal of the revolution from its very first principles.

Exam Tip
Excellent for tracing the corruption of the Seven Commandments. Each habit Old Major bans is later embraced by the pigs ("No animal shall sleep in a bed with sheets").
