How to use "oath" in a sentence

Now, if they would make the effort in good temper, could they not with nearly equal unanimity frame and pass a law by means of which to keep good that unanimous oath?

And should anyone in any case be content that his oath shall go un kept on a merely unsubstantial controversy as to HOW it shall be kept?

I take the official oath today with no mental reservations, and with no purpose to construe the Constitution or laws by any hypercritical rules

YOU have no oath registered in heaven to destroy the government, while I shall have the most solemn one to "preserve, protect, and defend it."

For I have sworn before you and Almighty God the same solemn oath our forebears prescribed nearly a century and three-quarters ago.
