There is one verse in the old testament which is quite intriguing; and it deals with the Son. Prov. 30,4 reads: "Who hath ascended up into heaven, or descended? who hath gathered the wind in his fists? who hath bound the waters in a garment? who hath established all the ends of the earth? what is his name, and what is his son's name, if thou canst tell?"
The context shows that it speaks about God. But who is this son mentioned in the old testament? Well, the text itself gives the answer - in Hebrew.
Well, this is not actual exegesis, but nevertheless fascinating. You can write down the words in a matrix and find some interesting patterns. For example with Prov. 30,4-6. If you write them down 22 letters in a row you end up with this pattern:
Horizontally it reads "the name" and vertically right through it in the form of a cross you can read "jesus" (of course in Hebrew): HaShem Yeshua. So does this text tell us the name of the Son of God?
