I was listening to a little JS Bach yesterday, including the song "Bereite Dir, Jesu, noch itzo die Bahn." (Prepare a way for yourself, Jesus)

Don't you think it should be "mir" (me) and not "dir" (you)? When I was in Sunday School, I was taught to think of Jesus making a way for us, blazing a trail, if you wish, to Heaven. Another example of that kind of thought is the spiritual, "Jesus walked that lonesome valley, had to walk it by himself."

This song appears in a cantata and was probably sung by a boy soprano from a destitute family. Reaching adulthood was hardly assured for him. Don't you think that praying for Jesus to make a way to Heaven for him makes more sense? Or is a construction like "bereite dir die Bahn?" something quite common in older German?
