You can freely and lawfully download a printable score for this Work from IMSLP - the Petrucci Music Library - though it may not be exactly the same as the one used to make the Midi Files below, and it probably won't be as good as a proper paid-for engraved and printed score.
There appear to be many different versions of this Work, with several clearly written by Handel himself. The IMSLP reference above includes both an Orchestral version (edited by Fr. Chrysander), in English and German, and a Vocal version (L. Hellwig), in German. There is also an unattributed English Vocal Score (similar to but not the same as the German one). This latter was used to make most of the Files below.
There is an excellent, and "complete", performance of this Work by the Philharmonia Baroque Orchestra & Chorale, under Nicholas McGegan, on YouTube starting here.
Here is a "clickable" Table of the available Midi Files for this Work (my thanks to Max, of Choralia, for much help with these). The Table entries in green relate to Sections which exist in the IMSLP Chrysander Orchestral Score but not in the Vocal Score version first used to make these Files.
