51 As soon as all the kings of the Amorites who were beyond the Jordan to the west, and all the kings of the Canaanites who were by the sea, heard that the Lord had dried up the waters of the Jordan for the people of Israel until they had crossed over, their hearts melted and there was no longer any spirit in them because of the people of Israel. 2 At that time the Lord said to Joshua, "Make flint knives and circumcise the sons of Israel a second time." 3 So Joshua made flint knives and circumcised the sons of Israel at Gibeath-haaraloth.[1] 4 And this is the reason why Joshua circumcised them: all the males of the people who came out of Egypt, all the men of war, had died in the wilderness on the way after they had come out of Egypt. 5 Though all the people who came out had been circumcised, yet all the people who were born on the way in the wilderness after they had come out of Egypt had not been circumcised. 6 For the people of Israel walked forty years in the wilderness, until all the nation, the men of war who came out of Egypt, perished, because they did not obey the voice of the Lord; the Lord swore to them that he would not let them see the land that the Lord had sworn to their fathers to give to us, a land flowing with milk and honey. 7 So it was their children, whom he raised up in their place, that Joshua circumcised. For they were uncircumcised, because they had not been circumcised on the way. 8 When the circumcising of the whole nation was finished, they remained in their places in the camp until they were healed. 9 And the Lord said to Joshua, "Today I have rolled away the reproach of Egypt from you." And so the name of that place is called Gilgal[2] 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.
