It's the perfect time for the people of Israel to recommit themselves to the Lord. And what better way to do that than for all the men who had been born in the wilderness, who had never been circumcised to be circumcised. Circumcision is the outward sign for the people of Israel that they are God’s and God’s alone. For whatever reason, in the wilderness, the practice had stopped, but now is the time for this next generation to commit themselves to the Lord, outwardly and inwardly. So, all the men get the snip with new flint knives. Then the people rest, recover and celebrate the first Passover in their new land.
