A total non-story by the looks of things.
Here is the best they come up with:
"...offers slightly more detail than the Greek translation of Matthew chapter 12. In verse 1 of the Greek translation, a sentence reads "at that time Jesus went through the grainfields on the Sabbath; and his disciples became hungry and began to pick the heads of grain and eat," while the Syriac translation discovered by Kessel ends "began to pick the heads of grain, rub them in their hands, and eat them". Wow!!!
