Tristis est anima mea
 

Latin:

Tristis est anima mea usque ad mortem.
Sustinete hic et vigilate mecum.
Nunc videbitis turbam quae circumdabit me.
Vos fugam capietis, et ego vadam immolari pro vobis.

English:

Sorrowful is my soul even unto death.
Stay here, and watch with me.
Now you shall see the mob that will surround me.
You shall take flight, and I shall go to be sacrificed.
