Oath

A true word needs no oath.Turkish.

An oath and an egg are soon broken.German.

An unlawful oath is better broken than kept.

He keeps his oath as a dog does his fast.German.

It is a great sin to swear unto a sin,
But greater sin to keep a sinful oath.Shakespeare.

Oaths are but words and words but wind.Butler.

’Tis not the many oaths that make the truth,
But the plain, single vow that is vowed true.Shakespeare.

To keep that oath were more impiety
Than Jeptha’s, when he sacrificed his daughter.Shakespeare.
