+ First Sorrowful Mystery: The Agony in the Garden
The First Sorrowful Mystery of the Rosary is the Agony in the Garden. It's a meditation on Christ's last night before he died, which he spent in the Garden of Gethsemane with the apostles.
The Agony in the Garden (Matthew 26:36-46)
On the night before his death, Christ went with the apostles to the Garden of Gethsemane to pray. There he wept as contemplated his upcoming death.
