Circumcision

No circumcision in the desert

Joshua 5:2 At that time the LORD said unto Joshua, Make thee sharp knives, and circumcise again the children of Israel the second time.

Joshua 5:3 And Joshua made him sharp knives, and circumcised the children of Israel at the hill of the foreskins.

Joshua 5:4 And this [is] the cause why Joshua did circumcise: All the people that came out of Egypt, [that were] males, [even] all the men of war, died in the wilderness by the way, after they came out of Egypt.

Joshua 5:5 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.

Joshua 5:6 For the children of Israel walked forty years in the wilderness, till all the people [that were] men of war, which came out of Egypt, were consumed, because they obeyed not the voice of the LORD: unto whom the LORD sware that he would not shew them the land, which the LORD sware unto their fathers that he would give us, a land that floweth with milk and honey.

Joshua 5:7 And their children, [whom] he raised up in their stead, them Joshua circumcised: for they were uncircumcised, because they had not circumcised them by the way.

So why is it that these people who dwelled in the desert did not circumcise their children? Verse 5 states that all the people coming up out of Egypt were in fact circumcised, but the children of those that came up were not. Essentially this means that for 400 years of slavery and suppression in Egypt, circumcision is upheld, but now that they are freed from oppression they discontinue simply because they are dwelling in the desert? And then just because they cross the Jordan, they all off a sudden are able to make sharp knives and circumcise again?
