These questions bubble to the surface when we delve into a fascinating passage from Shemot Rabbah, a collection of rabbinic interpretations of the Book of Exodus. It centers on a verse that seems straightforward, yet unfolds layers of complexity: "Beware of him and heed his voice; do not defy him, for he will not pardon your transgression, for My name is in him" (Exodus 23:21).

The "him" in this verse? It's an angel, a messenger sent by God. But here's where it gets interesting. The Holy One, blessed be He, is essentially telling Israel, "Be careful with this messenger." Why? Because, as Shemot Rabbah explains, this angel "does not renege on My mission; he is the attribute of justice." He's a stickler for the rules, embodying divine justice in its purest form.

“Do not defy him,” the verse continues. Shemot Rabbah interprets this in two ways. Firstly, it's a contrast to the past. God seems to say, "You have been defiant with the Lord" (Deuteronomy 9:7), and I would accept it from you. But now, with this angel, "do not defy him, for he will not pardon your transgression."

Secondly, and perhaps more provocatively, "do not defy [tamer] him" can be understood as "do not substitute him for Me." Don't replace God with the angel. It's a warning against misplaced worship. The text anticipates a potential misunderstanding: "Perhaps you will say: Since he is our guardian angel, it is him that we worship, and he will forgive our sins."

But no, the text insists, "for he will not pardon your transgression," unlike God, who is described as "Pardoning iniquity, and overlooking transgression" (Micah 7:18). There's a crucial distinction here. The angel is an extension of divine will, but not the source of forgiveness itself.

Shemot Rabbah takes it a step further, suggesting that misdirected worship could even cause God's name to be removed from within the angel. "For My name is in him," the verse reminds us. Why is God's name within the angel? Because, as we are told, ministering angels are sustained only from the aura of the Divine Presence. As it says in Nehemiah 9:6, "You sustain [meḥayeh] them all." Rabbi Ḥagai, quoting Rabbi Yitzḥak, emphasizes, "You are the life force [miḥya] for them all." The Maharzu commentary points out that meḥayeh generally means "bring to life," which is noteworthy considering angels don't die. The divine sustenance is not about resurrection, but about ongoing vitality.

Moreover, the text adds, the angel "incurs liability by their means." According to Maharzu, if the angel is worshipped, the worshippers will cause the angel himself to be punished. A stark warning about the dangers of idolatry, even when directed towards a seemingly divine figure.

The passage concludes with a crucial clarification. "For if you heed his voice and perform all that I will say" (Exodus 23:22). Notice it doesn't say "he will say," but rather, "I will say." If you accept the angel's message as if it were directly from God, then "I will be an enemy to your enemies" (Exodus 23:22). That is, "behold, I am sending an angel" (Exodus 23:20). The angel is a conduit, a messenger, but the ultimate source of authority and protection remains with God.

So, what can we take away from this intricate exploration of a single verse? Perhaps it's a reminder to be mindful of the messengers in our own lives – the people, ideas, and even institutions that guide us. To listen carefully, to discern the underlying truth, but never to mistake the messenger for the source. To remember that true allegiance lies with the divine, however we understand it, and that forgiveness ultimately comes from a source greater than ourselves. It's a balancing act between heeding guidance and maintaining our own discernment, a challenge as relevant today as it was centuries ago.
