"Some might think that Matthew 5:11-12 constitute the concluding Beatitude, since these verses begin with the words "blessed are you". But it is noteworthy that only here in the Beatitudes do we meet a verb in the second person (i.e, "blessed are you"). In addition there are36 (Greek) words in this Beatitude compared to a maximum of12words ( Matthew 5:10) in the preceding eight Beatitudes. It is reasonable to conclude that Matthew 5:3-10 are a self-contained introduction to the Sermon, while Matthew 5:11-12 commence the body of the Sermon." [1][source]
