51 So it was, when all the kings of the Amorites who were on the west side of the Jordan, and all the kings of the Canaanites who were by the sea, heard that the Lord had dried up the waters of the Jordan from before the children of Israel until we had crossed over, that their heart melted; and there was no spirit in them any longer because of the children of Israel. 2 At that time the Lord said to Joshua, "Make flint knives for yourself, and circumcise the sons of Israel again the second time." 3 So Joshua made flint knives for himself, and circumcised the sons of Israel at the hill of the foreskins. [1] 4 And this is the reason why Joshua circumcised them: All the people who came out of Egypt who were males, all the men of war, had died in the wilderness on the way, after they had come out of Egypt. 5 For all the people who came out had been circumcised, but all the people born in the wilderness, on the way as they came out of Egypt, had not been circumcised. 6 For the children of Israel walked forty years in the wilderness, till all the people who were men of war, who came out of Egypt, were consumed, because they did not obey the voice of the Lord--to whom the Lord swore that He would not show them the land which the Lord had sworn to their fathers that He would give us, "a land flowing with milk and honey." [2] 7 Then Joshua circumcised their sons whom He raised up in their place; for they were uncircumcised, because they had not been circumcised on the way. 8 So it was, when they had finished circumcising all the people, that they stayed in their places in the camp till they were healed. 9 Then the Lord said to Joshua, "This day I have rolled away the reproach of Egypt from you." Therefore the name of the place is called Gilgal [3] to this day.

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.
