It follows from this that the commentaries are deficient in order and sequence. The method which calls the writer to look at every step for spiritual meanings, combined with his own extraordinary fertility of imagination and wealth of matter, makes these books very disconnected. At each point a number of questions suggests itself as to possible meanings; a host of texts is brought at once from every part of Scripture to afford illustration, and these again have to be considered. Very modestly are the questions and themes introduced. The tone is as far as possible from being ex cathedra; it is rather that of a student groping his way, and asking at each step for assistance. And the great mass of the questions thus raised is left, apparently, unanswered. So that the work as a whole is rather a great collection of materials for future consideration than a finished treatise.
