1. There is insistence on this point with disregarding what I showed. Since there is repetition of this, I say more about it below.
2. Passover was in memorial to people of Israel being passed over with blood from a lamb on their doorpost, the meat was to be roasted, any of it remaining the next day was to be burned. So they had meat to eat for that day, but this which was told them did not require all to be eating meat, most chose to eat meat anyway, but one who chose not to wouldn't, in the way Daniel chose not to. This particular thing doesn't prove what Jesus did. Scripture passages conspicuously don't speak of meat at his last supper, the symbolic food that alone is mentioned is the bread and the wine, and bread and wine should still be used in remembrance.
3. You don't understand because you won't consider the scripture passages that I linked to, and look such up that you suggested you would. After asking if they had food there, Luke 24:42-43, so they gave him a piece of broiled fish and some honeycomb, he took and ate in their presence. That is the scripture, you can look into it. Does it mean he just ate fish? Why not that he just ate from the honeycomb? You can't tell. It doesn't seem likely that he ate both together, who would? You can guess he ate fish, but it just that guess. From what I know from scriptures and what is shown of Jesus, I very much suspect that he didn't have that.
4. This point really shows the passages I linked to aren't even looked at.
5. I speak for myself and don't answer for the OP. What I have said does have basis from scriptures, and what you use for your permission still is with you disregarding what is really said for you, and what you don't have permission in.
