With no break or warning, Exodus 4 drops us into one of the strangest, most disturbing and bewildering incidents in the Bible. Following the burning bush discussion, Moses is grudgingly making his way to Egypt. At an inn, he is waylaid by none other than the LORD, who intends to murder him. This is sudden and unexplained. Last the reader knew, Moses had been given his marching orders and was on the way to Egypt to meet his brother.
Suddenly: “And it came to pass by the way in the inn, that the LORD met him, and sought to kill him.” - Ex. 4:24 [KJV]
With YHWH and Moses apparently in the midst of a physical struggle, Moses’s wife Zipporah demonstrates some quick thinking. She picks up a flint stone and performs a jiffy circumcision by cutting her son Gershom’s foreskin off with a flint knife. She casts the foreskin at Moses’s feet. Seeing this, the LORD lets him go. Zipporah describes Moses as “a bloody husband” or” bridegroom of blood,” and doesn’t seem pleased in any way with the whole incident.
Following this confrontation, there don’t appear to be any hard feelings and there is no further discussion (that we are aware of) of the field circumcision incident.
There are lots of theories as to why this story exists in the first place, but no scholar or theologian has come up with anything convincing. However, if we bear in mind that we are dealing with a god who thinks mutilating male genitalia is part of a divine loyalty program, then the core of the tale seems fairly clear: God is pissed that Moses hasn’t circumcised his son or sons. We then are inclined to query why he hasn’t mentioned it in previous conversations. with Moses?
Since circumcision is the physical manifestation signifying the agreement between YHWH and the people he has chosen (about 800 years ago at the point of this story according to the Bible timeline) then what exactly is Moses’s relationship with YHWH at this point? If Moses is a practicing Yahwist, why isn’t Gershom circumcised. Did Moses over look this key requirement for Hebrew men? Was he even aware of it?
