Lukas 6:1-2

Orthodox Jewish Bible

6 And it came about on Shabbos that the Moshiach is passing through grain fields, and his talmidim were plucking and eating the heads of grain and rubbing them in their hands. [DEVARIM 23:25]

² Now some of the Perushim said, Why are you doing what is asur (impermissible) on Shabbos?
