Joshua circumcised the children of Israel (v. 3), not himself with his own hands, but he commanded that it should be done, and took care that it was done: it might soon be despatched, for it was not necessary that it should be done by a priest or Levite, but any one might be employed to do it. All those that were under twenty years old when the people were numbered at Mount Sinai, and not being numbered with them fell not by the fatal sentence, were circumcised, and by them all the rest might be circumcised in a little time. The people had promised to hearken to Joshua as they had hearkened to Moses (ch. i. 17), and here they gave an instance of their dutifulness by submitting to this painful institution, and not calling him for the sake of it a bloody governor, as Zipporah because of the circumcision called Moses a bloody husband.
