'Tree' in the Bible

Absalom was riding on his mule when he happened to meet David’s soldiers. When the mule went under the tangled branches of a large oak tree, Absalom’s head was caught fast in the tree. The mule under him kept going, so he was suspended in midair.

One of the men saw him and informed Joab. He said, “I just saw Absalom hanging in an oak tree!”

Joab said, “I’m not going to waste time with you!” He then took three spears in his hand and thrust them into Absalom’s heart while he was still alive in the oak tree,
