2nd Samuel 18:11

8 And the fighting went on over all the face of the country: and the woods were responsible for more deaths than the sword.

9 And Absalom came across some of David's men. And Absalom was seated on his mule, and the mule went under the thick branches of a great tree, and his head became fixed in the tree and he was lifted up between earth and heaven, and the beast under him went on.

10 And a certain man saw it and said to Joab, I saw Absalom hanging in a tree.

11 And Joab said to the man who had given him the news, If you saw this, why did you not put your sword through him, and I would have given you ten bits of silver and a band for your robe?

12 And the man said to Joab, Even if you gave me a thousand bits of silver, I would not put out my hand against the king's son: for in our hearing the king gave orders to you and Abishai and Ittai, saying, Take care that the young man Absalom is not touched.

13 And if I had falsely put him to death (and nothing may be kept secret from the king), you would have had nothing to do with me.

14 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.
