Exodus 4:24-26 involves a circumcision that happened under pressure from the threat of God’s judgment. It seems God was willing to kill Moses right after calling him to lead the Israelites out of Egypt. Why would he do that, even after he told Moses that it had to be him when Moses asked him to send someone else? This incident seems to imply a failure to circumcise in Moses’s family. Since circumcision was a part of the requirements for the Abrahamic covenant and Moses was leading the Israelites, it was important that he at least kept that rule.
