Emendemus in melius quae ignoranter peccavimus;
ne subito praeoccupati die mortis,
quaeramus spatium poenitentiae, et invenire non possimus.
Attende, Domine, et miserere; quia peccavimus tibi. (cf. Bar. 3:2)

English translation
Let us amend for the better in those things in which we have sinned through ignorance;
lest suddenly overtaken by the day of death,
we seek space for repentance, and be not able to find it.
Hearken, O Lord, and have mercy: for we have sinned against thee.
