As I read this passage vv.16-18 are the call of Simon and Andrew and vv. 19-20 are the call of James and John. Why does the context menu for a word in v. 18 show a turning point for all 4? Note that the pronoun they is tagged just for two.
Thanks MJ.This is a data error on our part. We have two events conflated into one. We have a case to make the split.
