It would be nice to have Cornelius Houtman's Exodus in the Historical Commentary on the Old Testament (4 Vols). it would be even nicer if somehow the electronic version made it affordable .
From Amazon's Product Description
This HCOT volume completes Houtman's monumental commentary on the Book
of Exodus. It covers the legal texts (the decalogue and the 'Book of
the Covenant') and most of the Sinai narrative. Beside a detailed and
deliberate interpretation it provides an invaluable guide to the
literature and the issues. The treatment of the 'tabernacle chapters' is
of particular interest. The corresponding sections about the
instructions for and the making of each part of the tabernacle are
discussed together and placed in side by side columns in the
translation. certainly make history' - M. Vervenne in Ephemerides
