God showed me a vision to review Ex 4:24-26. Reading this verse disturbed me without answers until I stumbled open an interesting web site which explained this to me….

Zipporah stubbornness

24 And it came to pass by the way in the inn, that the LORD met him, and sought to kill him.      

 

Inn There were no such places then on the way to Egypt, the Hebrew means "place for spending the night.".

Met him This reminds us of the Lord’s encounter with Elijah

Sought to kill him Why? Earlier in the story we read about Moses’ clear call from the Lord ch3. In the preceding verse we just read about the serious consequence awaiting Pharaoh’s disobedience. Behind him were the powers of darkness Satan and the rest of the evil angels. Moses would not be able to claim protection from the faithful angels while neglecting a known divine requirement. His death here in the desert would have been better than at the hands of the enemies of God after warning Pharaoh in Egypt. We might recall that the Lord dealt more directly with Moses than with others.

25  Then Zipporah took a sharp stone, and cut off the foreskin of her son, and cast it at his feet, and said, Surely a bloody husband art thou to me.      

Zipporah took She obviously was not pleased with the idea of circumcision and we may assume she had opposed her husband on this matter since the circumcision of Gershom, their older boy and that Moses shrank from further confrontation. Now angry at the Lord and Moses, she took the stone and performed the circumcision on Eliezer.

Sharp stone Flints were apparently used for this purpose. Perhaps she had one for preparing food.

Cast it at his feet Literally "made it touch his feet." So Moses may not have been standing but sick in bed. This could explain why He did not do the circumcision himself.

26  So he let him go: then she said, A bloody husband thou art, because of the circumcision.

So he let him go  Literally, "And he pulled back from him."

A bloody husband The word for husband here, chathan, is used to refer to a relative of a woman by marriage and may be translated "groom" in this circumstance. Compare the more common word for "husband" or special man, iysh. Zipporah was apparently not awed and repeated her verbal abuse.

The encounter must have developed Moses’ faith and dependence solely on the Lord. Also he would have realized that she was not ready to face the trials that would come in Egypt. It may have been at this point that he sent her back to Midian..
