The mitzvah of circumcision is ancient and, barring health issues, done for every Jewish baby boy. Some question the tradition and don’t want to circumcise their sons. While it seems a modern worry, the first person to seemingly neglect the mitzvah, was Moses.
In Exodus 4:24-26, we have a strange interlude amidst the Passover story, “At a night encampment on the way, יהוה encountered him and sought to kill him. So Zipporah took a flint and cut off her son’s foreskin, and touched his legs with it, saying, “You are truly a bridegroom of blood to me!” And when [God] let him alone, she added, “A bridegroom of blood because of the circumcision.”
What does this mean? In today’s Mishna we read:
Rabbi Yehoshua ben Korḥa says: Great is the mitzva of circumcision, as is evident from the fact that the punishment of Moses the righteous for not circumcising his son when he was capable of doing so was not postponed for even a full hour.
Moses hadn’t circumcised his sons!! The Gemara explains more:
GEMARA: It is taught in a baraita that Rabbi Yehoshua ben Korḥa says: So great is the mitzva of circumcision that all the merits that Moses our teacher accrued when he performed mitzvot did not protect him when he was negligent about performing the mitzva of circumcision, as it is stated: “And the Lord met him and sought to kill him” (Exodus 4:24).
Circumcision is so important that God was willing to kill Moses – before he freed the Hebrews from slavery – for neglecting it when he was only an hour late! But could Moses really not have intended to circumcise his sons?
Rabbi Yehuda HaNasi said: Heaven forbid that Moses our teacher was neglectful of the mitzva of circumcision. Rather, this is what he said: If I circumcise the child now and depart to begin my journey, it is a danger for the child, as it is stated: “And it came to pass on the third day, when they were in pain.”. If I circumcise him immediately and wait three days and only then embark on the journey, this is problematic, as the Holy One, Blessed be He, said to me: “Go, return into Egypt” (Exodus 4:19), i.e., go immediately.
So, he didn’t want the kid to be in pain on the journey but did not want to delay the journey, so he was postponing it, not neglecting it.
But according to this explanation, for what reason was Moses punished?
Because he was occupied with lodging first and did not immediately perform the mitzva of circumcision, as it is stated: “And it came to pass on the way at the lodging-place” (Exodus 4:24).
Now we hear more about the scene itself:
Rabban Shimon ben Gamliel says: It was not Moses our teacher that Satan wanted to kill, but rather, that infant who was not circumcised, as it is stated: “Surely a bridegroom of blood are you to me” (Exodus 4:25). Go out and see: Who does it make sense would be the one that is called the bridegroom in this instance? You must say this is the infant, since he is the one who entered the covenant of Abraham by means of the circumcision.
Rabbi Yehuda bar Bizna taught: At the time that Moses our teacher was negligent about the circumcision, the destructive angels named Af, meaning anger, and Ḥeima, meaning wrath, came and swallowed him, and only his legs were left outside. Immediately, “Zipporah took a flint, and cut off the foreskin of her son” (Exodus 4:25), and immediately “He let him alone” (Exodus 4:26).
So, I am picturing Moses being swallowed by snake like creatures and only his private parts being “unswallowed” so that Zipporah knew what to do. We should give her a shout out here. She was the daughter of a Midianite priest and did not hesitate to perform this task of dedicating her sons to the covenant.
So, what do we see? That circumcision is important to the Jewish people. We have a long history of parents questioning it (while Moses only likely questioned the timing and many today question it all together) and we also have a long tradition of the spouse who did not grow up Jewish being the one to make sure that all the proper Jewish rituals and rites are performed for the kids.
