Bach, St. Matthew Passion

The A section ends at 2:03, where it is followed by a long orchestral interlude before the B section begins at 2:35. At 3:09, there is another orchestral interlude that ends at 3:22 when the voice enters with a very short C section. When does that C section end, in other words, when does the melody and text from the A section return?
