`O vos omnes` is a responsory originally sung as part of Roman Catholic liturgies for Holy Week and now often sung as a motet. The text is adapted from the Latin Vulgate translation of Lamentations 112. It was often set as part of the Tenebrae Responsories for Holy Saturday.

Latin text
O vos omnes qui transitis per viam attendite et videte
Si est dolor similis sicut dolor meus.
Versus Attendite universi populi et videte dolorem meum.
Si est dolor similis sicut dolor meus.
