All the people that came out had been circumcised, but all the people born in the wilderness during the journey from Egypt had not. (NIV)
Though all the people who came out were circumcised, yet all the people who were born in the wilderness on the way after Israel came out of Egypt had not been circumcised. (AMP)
Now all the people that came out were circumcised: but all the people that were born in the wilderness by the way as they came forth out of Egypt, them they had not circumcised. (KJV)
