The opinion of Masius and O. v. Gerlach, that the expression “the second time” refers to the introduction of circumcision, when Abraham was circumcised with all his house, is very far-fetched. צרים חרבות are not “sharp knives,” but “stone knives,” which were used according to ancient custom (see at Exo 4:25), literally knives of rocks (the plural zurim is occasioned by charboth, as in Num 13:32, etc.; the singular might have been used: see Ewald, §270, c.).
Verse 3
Joshua had the circumcision performed “at the hill of the foreskins,” as the place was afterwards called from the fact that the foreskins were buried there.
Verses 4-7
The reason for the circumcision of the whole nation was the following: all the fighting men who came out of Egypt had died in the wilderness by the way; for all the people that came out were circumcised; but all that were born in the wilderness during the journey had not been circumcised (ממּצרים בּצאתם, on their coming out of Egypt, which only came to an end on their arrival in Canaan). They walked forty years in the wilderness; till all the people - that is to say, all the fighting men - who came out of Egypt were consumed, because they had not hearkened to the voice of the Lord, and had been sentenced by the Lord to die in the wilderness (Jos 5:6; cf. Num 14:26., Num 26:64-65, and Deu 2:14-16). But He (Jehovah) set up their sons in their place, i.e., He caused them to take their place; and these Joshua circumcised (i.e., had them circumcised), for they were uncircumcised, because they had not been circumcised by the way. This explains the necessity for a general circumcision of all the people, but does not state the reason why those who were born in the wilderness had not been circumcised. All that is affirmed in Jos 5:5 and Jos 5:7 is, that this had not taken place “by the way.” The true reason may be gathered from Jos 5:6, if we compare the statement made in this verse, “for the children of Israel walked forty years in the wilderness, till all the men that were capable of bearing arms were consumed ... unto whom the Lord sware that He would not show them the land promised to the fathers,” with the sentence pronounced by God to which these words refer, viz., Num 14:29-34. The Lord is then said to have sworn that all the men of twenty years old and upwards, who had murmured against Him, should perish in the wilderness; and though their sons should enter the promised land, they too should pasture, i.e., lead a nomad life, for forty years in the wilderness, and bear the apostasy of their fathers, till their bodies had fallen in the desert. This clearly means, that not only was the generation that came out
