This is one of my favorites for the Feast of the Sacred Heart, but I've been looking for a while for a chant piece to sing in alternatim since it's a bit short for an Offertory motet. The responsory for Terce, Tollite jugum, seems to be a good companion piece and is attached below (from the Liber Usualis 1961). The text for both is the text for the Alleluia verse for the Feast of the Sacred Heart.
