We can hardly believe that any Christian commentator would have written anything like this: "The reference to `the first month' here means that  Joshua 4:19 must be dated as late as 605 B.C."[5]   No Babylonian influence whatever is in this verse!  "The first month" here is the first month of the Jewish religious year, as indicated in  Exodus 12:2, to which this is a clear reference.  "Here is also a SUBSTANTIATION of the Pentateuchal testimony that a whole generation had expired since the observance of the original Passover."[6]   Such passages as these confirm absolutely the vital and intimate link between the Pentateuch and the Book of Joshua.
