Translation of the song lyrics Rex Tremendae - Aeternitas

Rex Tremendae (original)

Rex tremendae majestatis,
qui salvandos
salvas gratis,
salva me, fons pietatis.
Recordare, Jesu pie,
quod sum causa tuae viae:
ne me perdas
illa die.
Ingemisco tamquam reus:
Culpa rubet vultus meus:
supplicanti parce, Deus.
Preces mea non sunt dignae:
sed tu bonus fac benigne,
ne perenni cremer igne.

Rex Tremendae (translation)

King of tremendous majesty,
who saves
you save for free
save me, fount of pity.
Remember, Merciful Jesus
that I am the cause of your journey
don't lose
on that day.
I sigh like a guilty
Owning my
spare the supplicant, O God.
My prayers are not worthy
but you, you freeman, treat me kindly
eternal fire.
