Just after "Und neiget das Haupt und verschied" 

St John Passion is a long piece. I have one lonely solo of less than 10 seconds, but in a very critical scene just after the Evangelist has told "Und neiget das Haupt und verschied". Perhaps a little stressing... Luckily went ok today and in several performances along the years. And C# 4-3 to F# minor is not so convenient on a G-archlute... ;-)
