Joshua 5:3 - Joseph Benson’s Commentary on the Old and New Testaments

Joshua circumcised the children of Israel That is, he caused them to be circumcised, namely, such of them as were uncircumcised. And because it was to be done speedily, the passover approaching, it was necessary to use many hands in the business. Nor was it difficult to find them, as it did not signify by what hand the operation was performed. Fathers, mothers, relations, friends, might any of them perform, as well as the priests or Levites. Although it be not mentioned, it is more than probable that the Israelites beyond Jordan were circumcised at the same time, that they also might keep the passover.
