First, go to the East guard tower in Balmora. There, you will find the White Sword of Woe on top of a dresser. Try to get it in such a way that the guards won't notice. Then go to Suran and enter the guard tower near the huge bug. You can find the other White Sword of Woe under a bed. Also, if you aren't good with longswords, this cheat code isn't helpful to you unless you want money, because they sell for 16000 gold or something.
