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.

Then Joab said, I would have made it safe for you. And he took three spears in his hand, and put them through Absalom's heart, while he was still living, in the branches of the tree.

And the man said unto Joab, Though I were weighing upon my palm a thousand pieces of silver, yet would I not put forth my hand against the son of the king, - for, in our hearing, the king Charged thee and Abishai and Ittai, saying, Watch any man who would touch the young man Absolom.
