That appearance of God, which is recognized as very peculiar in the narrative, hinges on the nature of tiferet as the appearance of God that allows God to transgress his relationship with nature herself.
Does it actually use the word tiferet?
What does the midrash actually say?
What are you adding to it?
You're probably correct in your observation, but you're using the wrong Hebrew word to describe it.
This is to validate a theory you have about the choshen?
Professor Daniel Boyarin points out even more pointedly, is the extreme problem
Professor Daniel Boyarin the religious outcast who is not welcome to participate, religiously, with his community.
I'm pointing this out, because name dropping him, Professor Daniel Boyarin, does not produce credibility. It's no different than digging through a trash heap, looking for scraps of paper that were discarded, imagining that these are the holy words of sages, not garbage that was thrown away.
Professor Daniel Boyarin points out even more pointedly, is the extreme problem (so far as Judaism is concerned)
So far as Judaism is concerned, Daniel Boyarin does not speak for us. He is an outcast, a rebel. That needs to be stated clearly.
Outcast. Does not represent Judaism.
the fact that God tells Moses to lift the rod and part the sea, but then the text says God himself parts the sea? Did Moses or God part the sea? Did God use Moses? Did he need Moses? Did Moses' hand part the sea (through God's power) or did the rod part the sea?
The answer to your question is in Exo14:13-14. I'll show you. I think you'll like this. Very much.
Let's go back to the beginning of the thread?
In Isaiah 63:12, the arm of the Lord (spoken of earlier in 53:1, i.e., to whom will it be revealed) is, ironically, revealed to be in Moses' right hand. Which is not quite as peculiar as it seems if we exegete Exodus 4:16 properly. There (Exodus 4:16) God implies that, archetypically speaking, Aaron will be to Moses, as Moses was originally to be to God, God's mouthpiece. When Moses wigs out on God (4:13), God makes Moses represent God, and Aaron represent the mouthpiece God originally wanted Moses to be. Moses becomes the avatar of God, while Aaron is, ironically, an avatar of Moses.
14:13
ויאמר משה אל־העם אל־תיראו התיצבו וראו את־ישועת יהוה אשר־יעשה לכם היום כי אשר ראיתם את־מצרים היום לא תספו לראתם עוד עד־עולם׃
And Moses said to the people, Do not fear, stand still, and see "את־ישועת יהוה", which he will show to you today; for the Egyptians whom you have seen today, you shall never see them again.
14:14
יהוה ילחם לכם ואתם תחרשון׃
יהוה shall fight for you, and you shall hold your peace.
And that is the power of the Hebrew Torah
There's no need to do kabalistic back-flips.
