'Tree' in the Bible

Absalom happened to run into David's soldiers. While Absalom was trying to get away on his mule, it ran under the thick branches of a giant oak tree, and Absalom's head got caught in the tree! As his mule ran out from under him, Absalom was left hanging above the ground.

When one of the soldiers saw what had happened, he told Joab, "I saw Absalom stuck in an oak tree!"

"There's no reason to wait for you!" Joab retorted. Then he took three spears in his hand and stabbed Absalom in the heart while he was still alive, dangling from the branches of the oak tree.
