The Three Oaths are oaths made on the Oath Rod by Aes Sedai when they are raised from Accepted.

The oaths are: to speak no word that is not true, to make no weapon to be used by one man to kill another, and never to use the One Power as a weapon except against Shadowspawn, or as a last resort in defense of herself, her Warder, or another Aes Sedai.
