At Neot Kedumim most of the trees are identified by name and often with references to biblical events. I enjoyed seeing the Atad tree. The sign at the base of the tree explains an important biblical event which names the atad tree.
For ease of reading here is the first paragraph of the sign. Some of the spellings have been changed to make the information more easily understood by English readers.
A parable told by Jotham after the death of his father, Judge Gideon, criticizing his brother Abimelech’s rise to power after the latter brutally murdered all 70 of his other brothers “upon one stone” (Judges 9:5). The parable tells of the trees seeking to anoint a king. They ask the olive, fig, and grapevine who each refuse, wishing only to continue to bear their fruit. Eventually the Ziziphus spina-christi (atad), frequently – and misleadingly – mistranslated as a bramble, agrees to assume the role with devastating consequences: “let fire come forth from the atad” (Judges 9:15).
The Hebrew text uses the term atad for the plant. Common English translations include bramble, thronbush, and thorn bush. Some writers think of the atad as a tree, such as the one you see here.
The next photo shows some of the worthless fruit on the atad tree at Neot Kedumim. In contrast the fruit of the olive, the fig and the grape vine was very useful.
