A stranger's half-million-dollar boat is drifting towards the rocks. You save it - damaging your own boat and paying an emergency crew out of your own pocket. When you ask to be repaid, he answers: "Thanks, but I never asked you." Does he owe you anything?

The Talmud wrestled with exactly this: a man pours out his own wine to save a stranger's honey; a fugitive promises a ferryman a fortune to cross the river; two donkeys are swept away and only one can be saved. The rulings are surprising, and behind them sits a deep idea about what it really means to do someone a favour.

Count how many times Eliezer's camels are mentioned in Chayei Sarah.

Abraham fed strangers in the desert, then asked them to thank G-d. If they refused, he handed them a huge bill. Was that kindness, or a shakedown? The Talmud and Midrash tell a surprising story that raises an uncomfortable question: can you ever force someone to do the right thing?

If I really believe I'll win the lottery, will I?

Can you open a shop right next door to your competitor? In the free market, of course you can. But what does Jewish law say?

The Talmud (Bava Batra 21b) records Rav Huna's ruling: if your neighbour opens a mill next to your mill, you can stop him, because "you're cutting off my livelihood." But is that the final word? Through fish traps, free lollies for kids, and rival bathhouses, the Sages pull that ruling apart.

Abraham discovered G-d at the age of three, smashed his father's idols and risked his life rather than worship false gods. Yet the Torah barely mentions any of these extraordinary achievements.

Instead, Abraham's story begins with two simple words: Lech Lecha, “Go for yourself.”

Why does the Torah overlook Abraham's spiritual greatness? And what does this reveal about the fundamental difference between the Jewish relationship with G-d and that of the rest of humanity?

A fascinating teaching of the Lubavitcher Rebbe reveals what truly makes a Jew Jewish, and why our connection with G-d goes deeper than faith, understanding or even religious observance.

You booked an electrician for a full day's work: $1,200. He shows up on time, ready to go. But the equipment he came to install never arrived. He says you owe him for the full day anyway. Do you?

The Talmud (Bava Metzia 76b) has a clear answer, and it comes down to one question: who had the information? If you knew - or should have known - that the job couldn't go ahead and you didn't warn him, his lost day is your loss. But if he could easily have found other work that morning, you don't owe him a cent. You owe him something else: an apology. In Jewish law a "grievance" is a real claim. Not in dollars, but in how you treat people.

Noah's Ark was home to thousands of creatures for an entire year. But according to the Talmud, some of those creatures couldn't possibly live that long. So how did they survive?

A fascinating question leads us from the Talmud to the Rebbe's writings, revealing a surprising insight into the nature of time itself.

And the Baal Shem Tov takes the story one step further, showing us how we can enter Noah's Ark today.
