4 Now this is why he did so: All those who came out of Egypt-all the men of military age-died in the wilderness on the way after leaving Egypt.
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.
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.
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.
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.
4 Joshua had to circumcise them because all the men who were old enough to fight in battle when they left Egypt had died in the wilderness.
Matthew Henry's Commentary on Joshua 5:4
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.
