“Drawing a bow means taking and losing lives. But Father, if I do not take a life... If I do not take a life, I cannot go on living.”
The words of god conveyed to Yona through the priest Ik-Soo are to find the four Dragon Warriors of Kouka Kingdom's Legend of the Four Dragons.
If you miss the priest, you can 
return to those mountains anytime.
إذا كنت تشتاق للكاهن، يمكنك العودة 
إلى تلك الجبال متى أردت
Wenn du den Priester vermisst,
kannst du ruhig zurückgehen.
Si extrañas al monje, puedes 
volver a esas montañas.
Si echas de menos al monje, puedes 
volver a esas montañas.
Si le prêtre te manque,
tu peux rentrer quand tu veux
Se ti manca il sacerdote,
puoi tornare da lui quando vuoi.
Se sentir falta do sacerdote, 
sempre pode voltar às montanhas.
