Definition: The Hebrew word "Alysoun" in the King James Version (KJV) is not a commonly used name or term, but it appears to be a Greek term meaning "thorn tree." It's possible that this name was adopted for historical reasons during the time when the Israelites were being persecuted by Assyria. However, without more context, it's hard to provide an accurate definition of this particular word. The term "Alysoun" could refer to a variety of things based on its meaning in different contexts and its specific use within the Bible or Jewish religious practices. In some instances, "Alysoun" may have been used as a name for a type of tree that was specifically planted in honor of a king in Israel during the Babylonian exile (the 'A' in Alysoun can be read as 'King', implying the tree's connection to an actual king or royal figure). In other cases, it could also refer to a type of thorn that is commonly used in Jewish tradition and has been associated with the idea of sin, death, and resurrection.
