Original Draft of the Declaration of Independence,

From the original draft of the Declaration of Independence, by Jefferson, but removed from the final draft. It is an attack upon the King and his direct and indirect participation in the slave trade.

rights of life and liberty in the persons of a distant people who never offended

exciting those very people to rise in arms among us, and to purchase that
liberty of which he has deprived them, by murdering the people upon whom
he also obtruded them; thus paying off former crimes committed against the
liberties of one people, with crimes which he urges them to commit against
the lives of another....
