The Talmud reports that Mar Ukva, a respected rabbi, would not eat dairy after eating meat at the same meal, and had a father who would wait an entire day after eating meat before eating dairy produce.[1] Jacob ben Meir speculated that Mar Ukva's behaviour was merely a personal choice, rather than an example he expected others to follow, but prominent rabbis of the Middle Ages argued that Mar Ukva's practice must be treated as a minimum standard of behaviour.
