“See, I am sending an angel ahead of you to guard you along the way and to bring you to the place I have prepared.
(Exodus 23:20)
In another thread some evidence is given to raise the question: was the figure of the precursor/messenger of Jesus required simply by the prophecy in Exodus 23:20 or for a different reason (other OT prophecies, rivalry with the John sect, a historical John who baptized really a historical Jesus, etc) ?
The problem is made more difficult since the Angel of YHWH described in Exodus 23:20 is easily seen as the biblical Joshua. The Gospel of 12 holy Apostles (syriac version) seems to reserve that prophecy for Jesus. But a problem arises: is Jesus the Angel of YHWH or is he the person who has the Angel of YHWH as his (more or less divine) precursor?
In Exodus 23:20 YHWH is addressing Moses, but obviously Moses stands for the entire Israel, since the Angel of YHWH has to precede him as an entire group. Hence, was Jesus seen in the "servant" Israel or in the his leader (=who leads him) i.e. the Angel of YHWH? A distinction between the Angel and who is introduced by the Angel is required.
Only in a second place the Angel of YHWH is combined with the figure of Eliah as precursor of the Messiah. Frankly, I wonder why so much insistence is given on John as Elijah etc and not on John as the Angel of YHWH seen in Exodus 23:20. I have the strong suspicion that that insistence is all mere apologetics.
Once explained the need of a precursor with "the name of YHWH in him", the name of John ("YHWH gives grace") was imposed naturally. Note also the deliberate contrast between what the Angel of YHWH will do (death and destruction on the enemies of Israel in Canaan) and what John will do (giving grace by the his baptism).
John the Baptist was confused with the new Jesus/Joshua because he was identified with the Angel of YHWH who was already easily confused with the old Jesus/Joshua.
Is it only a coincidence the fact that the person who had to play the role of the Angel of YHWH was just one with the "Name of YHWH in him" ? Did a historical John exist independently from that role and from that name that were required per Exodus 23:20?
