“For the land you are going in to possess is not like the land of Egypt from which you came. There you planted your seed and watered it by foot, like a vegetable garden.
If the Egyptians do not go up and celebrate, they will have no rain. Instead, there will be the plague that Adonai will inflict on the nations that do not go up to celebrate Sukkot.
and so that you may prolong your days on the land that Adonai swore to give to your fathers and to their descendants—a land flowing with milk and honey.
