Who was Yehoshua ben Galgula ? I will tell you the answer in just a few moments but you should first listen to this story. About ten years ago I got to be a tour guide for this amazing family, the Wilson's. After a week of touring almost the whole country and on the way to the airport I asked them the following question, I asked them: “Do you have any idea of how the bees find the nectar?” now, I know what you must be thinking to yourselves...they thought the same thing, until I started giving them the explanation. The bees fly out of the hive and travel a distance of 3.10 miles and search for nectar in the flowers. When they travel back to the hive an amazing thing happens next, the bees who found the less amount of nectar dance kind of slow and sad but the bees who found a high amount of nectar are dancing rapidly and joyfully and that's how the other bees know which bee they need to follow and obviously it will be after the bee that found the biggest amount of nectar

=and then, I looked directly into the eyes of the Wilson's family members and I told them: “Do you know why I'm telling you this story right here at this very moment, a second away from leaving Israel and take off?”
