HERE is a link to a post on the blog Scotteriology that analyzes a video of Mark Driscoll.  Driscoll is attempting to show that the Trinity is in Genesis 1, but has to pull some pretty major stretches to reach his conclusion.  For one, he says the word “God” is plural but doesn’t deal with the fact that it takes a singular verb.  Anyone with even a cursory knowledge of Biblical Hebrew should be able to figure this out.  The post that I link to above deals with the video in a lot more detail (e.g.  how Driscoll completely misses on the dating of a Targum that he is discussing – off by about 400 years).
