Benedicam Dominum, the opening verse of Psalm 33 (Septuagint numbering), is used for both the Responsorium breve for Tuesday Vespers (Ant. Mon. 1934 p 136) and (with the following verse "In Domino laudabitur") as the Gradual for Pentecost XII.
There is also an Offertory, Benedicam Dominum qui mihi tribuit for the Tuesday after Lent II (GR p. 116)
