And Joshua made him sharp knives, and circumcised the children of Israel at the hill of the foreskins.
All Commentaries on Joshua 5:3 Go To Joshua 5
Justin Martyr
AD 165
Joshua is reputed to have circumcised the people a second time by means of stone knives (which was a sign of that circumcision by which Jesus Christ himself has cut us off from idols made of stone and other materials) and to have gathered together those who everywhere from the uncircumcision (that is, from worldly error) were circumcised with stone knives, namely, the words of our Lord Jesus. For I have already pointed out that the prophets used to call him figuratively a stone and rock. By the stone knives, therefore, we understand his words, by which so many who were in error have been circumcised from their uncircumcision with the circumcision of the heart. From that time God commanded through Jesus that they who had the circumcision which began with Abraham should be circumcised again with the circumcision of the heart, for he said that Joshua performed a second circumcision with stone knives upon those who entered into the Holy Land.
