Pie Jesu is an 800 year old Catholic prayer/hymn.
It is the final verse of the great Dies Irae, the sequence from the Requiem Mass.
No prayer of the Catholic sacred liturgy has been set to music more often over the centuries than the Dies Irae.
The original text, derived from the Dies irae sequence, is as follows:
| Pie Jesu Domine, | Kind Lord Jesus, |
| dona eis requiem. | grant them rest. |
| Pie Jesu Domine, | Kind Lord Jesus, |
| dona eis requiem sempiternam. | grant them everlasting rest. |

| Qui tollis peccata mundi; | You who take away the sins of the world; |
| Dona eis requiem, | Grant them peace, |
| Dona eis requiem. | Grant them peace, |
| Agnus Dei, Agnus Dei, | Lamb of God, Lamb of God, |
| Agnus Dei, Agnus Dei, | Lamb of God, Lamb of God, |
| Qui tollis peccata mundi; | You who take away the sins of the world; |
| Dona eis requiem, | Grant them peace, |
| Dona eis requiem. | Grant them peace, |
| Sempiternam, sempiternam requiem. | Peace everlasting, everlasting. |
