The Appeal To Peter

You quote, to vindicate your meat,
The text, “Rise, Peter, slay and eat.”
Well, if such precept you’d obey,
Why don’t you rise, yourself, and slay?
To eat, it seems, you’re more than willing,
When other folk have done the killing:
But that injunction given to Peter
Was not to be an idle eater;
It bade him rise—take knife from shelf,
And do the bloody job himself.
