I believe Kudaen gyote opjiman

I believe na-e-ge orun girun

Modu jinagan ku gi-ok-sukeso
naega nalrul apuge hamyo nunmurun manduljyo

Namankum ulji anh-kirul kudae-manun
nunmul obshi nal pyonhage ttona-jugirul
Onjen-ga tashi-dura ol
kudae-ranun gyol algiye / nan mitko itkiye
Kidaril-keyo nan kudae-yo-ya-man hajyo

I believe naega apa-halkkabwa

Jakku momchurun nae nunkil sokeso

Namankum ulji anh-kirul kudae-manun

Kidaril-keyo nan kudae-yo-ya-man hajyo

Na kudae alki chon i sesangdo / irohke nunbusyon-nunji
Ku hanul araeso ijen / nunmulro ramgyocho-jiman

Saranghan iyumanuro / tto haruga chinagago

Nan kudaeyoyaman hajyo
