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.
8. when they had done circumcising all the people—As the number of those born in the wilderness and uncircumcised must have been immense, a difficulty is apt to be felt how the rite could have been performed on such a multitude in so short a time. But it has been calculated that the proportion between those already circumcised (under twenty when the doom was pronounced) and those to be circumcised, was one to four, and consequently the whole ceremony could easily have been performed in a day. Circumcision being the sign and seal of the covenant, its performance was virtually an investment in the promised land, and its being delayed till their actual entrance into the country was a wise and gracious act on the part of God, who postponed this trying duty till the hearts of the people, animated by the recent astonishing miracle, were prepared to obey the divine will.
they abode in their places … till they were whole—It is calculated that, of those who did not need to be circumcised, more than fifty thousand were left to defend the camp if an attack had been then made upon it.
