The most obvious answer is Jesus' words to his disciples at the Last Supper, in Matthew's version:


  this is my blood of the covenant, which will be shed on behalf of many for the forgiveness of sins.


(Matthew 26:28, New American Bible Revised Edition) 

Has Jesus ever directly said he would die as a voluntary sacrafice? If so, wasn't it double sense?
I am using gb4e for glossing examples in my thesis. I would like to set the example number back to zero for an appendix. I assume some variation of Alan Munn's solution at gb4e enumeration format might work for me, but but how to format it so that it only affects the one chapter, rather than all chapters.
