According to Devarim 23:25 כִּי תָבֹא בְּכֶרֶם רֵעֶךָ, וְאָכַלְתָּ עֲנָבִים כְּנַפְשְׁךָ שָׂבְעֶךָ; וְאֶל-כֶּלְיְךָ, לֹא תִתֵּן.
Where is there a discussion where one can understand Devarim 23:25 fully? For example, is it implied in this passage the size of the vineyard, if it is an open or enclosed vineyard, how often one can do this, etc...? If not, then one might see a number of problems:
such as, but not limited to: no knocking at the vineyard entrance, if any, needed, that is, no permission to enter the vineyard needed, just eat all you can, as long as each fruit goes directly to your mouth and not into a container, and you can do this any day of the week, except shabbat, etc....
An observant vineyard-owner can even deduce from this passage that s/he can not injure or kill anybody who enters, i.e. trespass, his/her vineyard (so a vineyard trespasser is better off selecting vineyards owned by observant Jews in States where one can pull a gun on a trespasser, no?)?
