It's a cappella plus (un-figured) Continuo essentially doubling the 
choir bass:

The presence of the Continuo should mean "let the continuo band play 
along"; while there is no explicit indication as to which instrument(s) 
should be used (at least in the Bärenreiter score), the repeated 
crochets-with-slurs clearly indicate that Bach expects a bowed instrument.

In Herreweghe's rendering, I hear cello (original continuo line) plus 
organ (playing the complete chords).
