Benedixisti (the first line of text translates to "Lord, thou hast blessed thy land”) is an aptly celebratory Offertory for Gaudete Sunday. While brief, it is a lovely work that translates well to Brass choir or brass octet.

 

Benedixisti has been available from Concordia Pulishing House since 1969 and can be found at:

Benedixisti is not recorded as a sextet, and the mP3 is a FINALE MIDI audio extract (not a great sound, but you get the idea of what the piece sounds like).
