Jos 5:2-12. CIRCUMCISION IS RENEWED.

      2. At that time--on the encampment being made after the passage.
      the Lord said unto Joshua, Make thee sharp knives--Stone knives, collect and make them ready. Flints have been used in the early times of all people; and although the use of iron was known to the Hebrews in the days of Joshua, probably the want of a sufficient number of metallic implements dictated the employment of flints on this occasion (compare Ex 4:25).
      circumcise again the children of Israel the second time--literally, "return and circumcise." The command did not require him to repeat the operation on those who had undergone it, but to resume the observance of the rite, which had been long discontinued. The language, however, evidently points to a general circumcising on some previous occasion, which, though unrecorded, must have been made before the celebration of the passover at Sinai (compare Ex 12:48; Nu 9:5), as a mixed multitude accompanied the camp. "The second time" of general circumcising was at the entrance into Canaan.
