Where it comes from
It opens a moleben, a short service of prayer cut down from the morning service of feast days. A priest sings a moleben most often when someone asks for one. This one is “for those in sorrows and various hardships”, and its book names no author.

The same cry all through
All through the service’s canon, a long hymn in several parts, the people answer: “Merciful Lord, have mercy on Your servants who wait for mercy.” Its Gospel is Jesus’s call to all who are weary and burdened, the words this short hymn takes up.

The Scripture in it
Save Your people and bless Your inheritance; shepherd them and carry them forever.
Come to Me, all you who are weary and burdened, and I will give you rest.
