2 Samuel 4:9

6 And they came thither into the midst of the house, [as though] they would have fetched wheat; and they smote him under the fifth [rib]: and Rechab and Baanah his brother escaped.

7 For when they came into the house, he lay on his bed in his bedchamber, and they smote him, and slew him, and beheaded him, and took his head, and gat them away through the plain all night.

8 And they brought the head of Ishbosheth unto David to Hebron, and said to the king, Behold the head of Ishbosheth the son of Saul thine enemy, which sought thy life; and the LORD hath avenged my lord the king this day of Saul, and of his seed.

9 And David answered Rechab and Baanah his brother, the sons of Rimmon the Beerothite, and said unto them, [As] the LORD liveth, who hath redeemed my soul out of all adversity,

10 When one told me, saying, Behold, Saul is dead, thinking to have brought good tidings, I took hold of him, and slew him in Ziklag, who [thought] that I would have given him a reward for his tidings:

11 How much more, when wicked men have slain a righteous person in his own house upon his bed? shall I not therefore now require his blood of your hand, and take you away from the earth?

12 And David commanded his young men, and they slew them, and cut off their hands and their feet, and hanged [them] up over the pool in Hebron. But they took the head of Ishbosheth, and buried [it] in the sepulchre of Abner in Hebron.
