The name of the most frequently mentioned river in the Bible, the Jordan (ירדן) (yardēn) river, comes from the Hebrew verb ירד (yāraḏ), which means “to go down.”
The flow of the Jordan (ירדן) river can help you remember the origin of its name since the river “goes down” from its origin near Mount Hermon southward through the Sea of Galilee until it ends in the Dead Sea, which at 1,412 feet below sea level is the lowest land-based point on Earth.
