              | {222} Tu Trinitatis Unitas.
 | 
            
              | MAY the dread Three in One, who sways
 | 
            
              | All with His sovereign might, | 
            
              | Accept us for this hymn of praise, | 
            
              | His watchers in the night. | 
            
              | For in the night, when all is still
 | 
            
              | We spurn our bed and rise, | 
            
              | To find the balm for ghostly ill, | 
            
              | His bounteous hand supplies. | 
            
              | If e'er by night our envious foe
 | 
            
              | With guilt our souls would stain, | 
            
              | May the deep streams of mercy flow, | 
            
              | And make us white again; {223} | 
            
              | That so with bodies braced and bright,
 | 
            
              | And hearts awake within, | 
            
              | All fresh and keen may burn our light, | 
            
              | Undimm'd, unsoil'd by sin. | 
            
              | Shine on Thine own, Redeemer sweet!
 | 
            
              | Thy radiance increate | 
            
              | Through the long day shall keep our feet | 
            
              | In their pure morning state. | 
            
              | Grant this, O Father, etc.
