And it came to pass on the second sabbath after the first, that he went through the grainfields; and his disciples plucked the ears of grain, and did eat, rubbing them in their hands.

Isodore of Seville
AD 636
He says, On the second-first, because it was the second day of the Passover, but the first of unleavened bread. Having killed the passover, on the very next day they kept the feast of unleavened bread. Andit is plain that this was so from the fact, that the Apostles plucked ears of corn and ate them, for at that time the ears are weighed down by the fruit.
