"10 commandments humorously done in verse" joke

by Arthur Hugh Clough (1819-1861) Thou shalt have one God only, who
Would be at the expense of two?
No graven images may be
Worshipped, except the currency:
Swear not at all, for thy curse
Thine enemy is none the worse:
At church on Sunday to attend
Will serve to keep the world thy frield:
Honour thy parents; that is, all
From whom advancement may befall:
Thou shalt not kill; but needst not strive
Officiously to keep alive.
Do not adultery commit
Advantage rarely comes of it.
Thou shalt not steal; an empty feat,
When it's so lucrative to cheat.
Bear not false witness; let the lie
Have time on its own wings to fly:
Thou shalt not covet: but tradition
Approves all forms of competition.
The sum of all is, thou shalt love,
If any body, God above:
At any rate shall never labour
More than thyself to love thy neighbour.
