And it came to pass -- he is going along on the sabbaths through the corn-fields -- and his disciples began to make a way, plucking the ears,

And it came to pass, on the second-first sabbath, as he is going through the corn fields, that his disciples were plucking the ears, and were eating, rubbing with the hands,

What then was your blessedness? for I bear you witness that, if possible, plucking out your own eyes ye would have given them to me.
