I probably shouldn't have started this game with that picture - but it was on my mind.
Our English word "wine" - means the fermented juice of a fruit - traditionally - grapes. "New wine" and "Old wine" (in our culture) refers to how long the wine has aged - as a fermented wine.
This being established as obvious - a wine skin that is "old" and empty will not burst when "new" wine is added to it - because for it to burst it must ferment further - releasing CO2. But since it is already fermented out - it simply will not do this. An old wine skin filled with "new" (but already fermented) wine will not burst and break. The teaching of Yeshua in Matthew 9:17 used to confuse me because I didn't understand the fermentation process at that time.
I make beer on a regular basis and sometimes wine. The making of these products release a lot of gas - enough pressure to cause a wine skin to break
- but only if...
The "New Wine" by definition - is not yet fermented - ie: has not been turned into an alcoholic product through the conversion of it's sugars.
How this relates to the picture:
Wine (as an alcoholic product) couldn't have been consumed at the Last Supper/First day of Unleavened bread. "New Wine" must be un-fermented "fruit of the vine".
Further:
The law of the Feast of Unleavened doesn't just apply to bread. It applies to everything made with yeast. That includes wine - be it natural yeast arising from the juice/grape itself - or added yeast. Exodus 12:15, 12:19
Now after explaining it I know I shouldn't have started the game off this way, as it's likely to start a debate, lol.
ImaginaryDay2 - you may supply the next picture since you gave part of the right answer (sorry ImAlive - I don't read Dutch and according to Google translate you misspelled "gist" as well).
