Ordain

To ordain is to make an ordinance, to enact a law.

In the Constitution of the United States, the preamble declares that the people "do ordain and establish this constitution for the United States of America." The 3rd article of the same Constitution declares, that "the judicial power shall be vested in one supreme court, and in such inferior courts as the congress may from time to time ordain and establish."
