/*
	Oce nas,
	koji si na nebesima,
	da se sveti ime Tvoje,
	da dodje carstvo Tvoje,
	da bude volja Tvoja,
	i na zemlji, kao i na nebu.
	
	Hleb nas nasusni daj nam danas,
	i oprosti nam dugove nase,
	kao sto i mi oprastamo duznicima svojim,
	i ne uvedi nas u iskusenje,
	no izbavi nas od zloga.
	
	Jer je Tvoje Carstvo,
	i sila, i slava,
	u vekove vekova.
	
	Amin.
