Aspérges me, Dómine, hyssópo et mundábor:
lavábis me, et super nivem dealbábor.

Miserére mei, Deus,
secúndum magnam misericórdiam tuam.

Glória Patri, et Fílio, et Spirítui Sancto.
Sicut erat in principio, et nunc, et semper,
et in saécula saeculórum. Amen.

Translation

Thou shalt sprinkle me, O Lord, with hyssop, and I shall be cleansed:
Thou shalt wash me, and I shall be made whiter than snow.

Have mercy on me, O God,
according to Thy great mercy.

Glory be to the Father, and to the Son, and to the Holy Spirit.
As it was in the beginning, is now, and ever shall be,
world without end. Amen.
