Shlama Joel,
I'm really enjoying the new book, you & Walid did a great job. It's a got some typos & formatting problems, but the content is really good & covers everything I think of.
If you two are ever going to release a 2nd edition, I think there are a few sections that you can expand on. Eg: your mention of the Aramaic word-play of "mev arav/arab" in Daniel 2 concerning the "feet & toes of clay". You might want to check out the Aramaic Peshitta (OT & NT) as well as the Targums. The Peshitta NT has plenty of these kinds of word-plays, especially in Yeshua's parables, eg:
Luke 8:11 "This is the meaning of the parable (mithla): the seed is the word (miltha) of God."
I can give you some links if you like.
