So Joshua made flint knives, and circumcised the Israelites at Gibeath-haaraloth.
But Zipporah took a flint and cut off her son's foreskin, and touched Moses' feet with it, and said, “Truly you are a bridegroom of blood to me!”
Then Jesus told his disciples, “If any want to become my followers, let them deny themselves and take up their cross and follow me.
At that time the Lord said to Joshua, “Make flint knives and circumcise the Israelites a second time.”
This is the reason why Joshua circumcised them: all the males of the people who came out of Egypt, all the warriors, had died during the journey through the wilderness after they had come out of Egypt.
