That would be hard to find in the US Constitution. But not in the Declaration of Independence. Alas, the latter is not law.
We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.
The Declaration is law, but the part you are referring to is the preamble of the law.
