Both are correct. The version in the paq'batlh is older. Traditionally, the phrase lIjlaHbogh pagh is applied to Kahless only, while the newer lIjlaHbe'bogh vay' may be applied to Kahless and other leaders/heroes as well. It would be a sign of extreme arrogance or disrespect to use the pagh version for anyone other than Kahless. (through David Yonge-Mallo, message to the mailing list of 10/10/2021)
