For those of you who are interested in the linguistics of biblical languages or just Linguistics as a discipline of study, do yourselves a favor and get, if you can, Halliday's book, Explorations in the Functions of Language. If you can't find it (or it's being sold for much too high a price), the essays may be found reprinted in volume 10 of the series entitled "The Complete Works of M. A. K. Halliday," which is edited by Jonathan Webster.
