Verse 5. - Now all the people that came out were circumcised. The Hebrew of this passage (which runs literally thus - "Now circumcised had they been, all the people who were going forth") is sufficient to refute the idea that there was a great circumcision of the people under Moses, on account of the neglect of the rite in Egypt. For, before the exodus, Moses was not in a position to perform any general act of this kind, as the history plainly shows, while after it such a rite could not have taken place, since the Hebrew הָיוּ denotes a state of things which was completed at the time spoken of, and therefore must here be rendered (as above) by the pluperfect. Them they had not circumcised. Here again the Hebrew is used of the perfected action, and is therefore rightly rendered by our version, giving the idea that the Israelites who were born in the wilderness had not been circumcised up to the point which our history has now reached. See also ver. 7, where the same construction is found.

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.Now all the people that came out were circumcised,.... All that came out of Egypt, and males, were circumcised, whether under or above twenty years of age; for though it is possible all were circumcised before they came out of Egypt, which favours the opinion of Dr. Lightfoot, that they might be circumcised during the three nights' darkness of the Egyptians, when they could take no advantage of it, as Levi and Simeon did of the Shechemites; and which seems more probable than that it should be on the night they came out of Egypt, when many must have been unfit for travelling, and seems preferable to that of their being circumcised at Mount Sinai, which was a year after their coming out of Egypt:

but all the people that were born in the wilderness by the way, as they came forth out of Egypt, them they had not circumcised; the reasons of which neglect; See Gill on Joshua 5:2. The phrase, "by the way", seems to point at the true reason of it, at least to countenance the reason there given, which was on account of their journey; that is, their stay at any place being uncertain and precarious; so the Jews say (z), because of the affliction or trouble of journeying, the Israelites did not circumcise their children. This is to be understood of all males only born in the wilderness, they only being the subjects of circumcision.
