2 At that time God said to Joshua, "Make stone knives and circumcise the People of Israel a second time." 3 So Joshua made stone knives and circumcised the People of Israel at Foreskins Hill. 4 This is why Joshua conducted the circumcision. All the males who had left Egypt, the soldiers, had died in the wilderness on the journey out of Egypt. 5 All the people who had come out of Egypt, of course, had been circumcised, but all those born in the wilderness along the way since leaving Egypt had not been. 6 The fact is that the People of Israel had walked through that wilderness for forty years until the entire nation died out, all the men of military age who had come out of Egypt but had disobeyed the call of God. God vowed that these would never lay eyes on the land God had solemnly promised their ancestors to give us, a land flowing with milk and honey. 7 But their children had replaced them. These are the ones Joshua circumcised. They had never been circumcised; no one had circumcised them along the way. 8 When they had completed the circumcising of the whole nation, they stayed where they were in camp until they were healed. 9 God said to Joshua, "Today I have rolled away the reproach of Egypt." That's why the place is called The Gilgal. It's still called that.

Commentary on Joshua 5:1-9
(Read Joshua 5:1-9)
How dreadful is their case, who see the wrath of God advancing towards them, without being able to turn it aside, or escape it! Such will be the horrible situation of the wicked; nor can words express the anguish of their feelings, or the greatness of their terror. Oh that they would now take warning, and before it be too late, flee for refuge to lay hold upon that hope set before them in the gospel! God impressed these fears on the Canaanites, and dispirited them. This gave a short rest to the Israelites, and circumcision rolled away the reproach of Egypt. They were hereby owned to be the free-born children of God, having the seal of the covenant. When God glorifies himself in perfecting the salvation of his people, he not only silences all enemies, but rolls back their reproaches upon themselves.
