New King James Version (NKJV)
2 Samuel 4
7 For when they came into the house, he was lying on his bed in his bedroom; then they struck him and killed him, beheaded him and took his head, and were all night escaping through the plain.
8 And they brought the head of Ishbosheth to David at Hebron, and said to the king, "Here is the head of Ishbosheth, the son of Saul your enemy, who sought your life; and the Lord has avenged my lord the king this day of Saul and his descendants."
9 But David answered Rechab and Baanah his brother, the sons of Rimmon the Beerothite, and said to them, "As the Lord lives, who has redeemed my life from all adversity,
10 when someone told me, saying, ’Look, Saul is dead,’ thinking to have brought good news, I arrested him and had him executed in Ziklag--the one who thought I would give him a reward for his news.
11 How much more, when wicked men have killed a righteous person in his own house on his bed? Therefore, shall I not now require his blood at your hand and remove you from the earth?"
12 So David commanded his young men, and they executed them, cut off their hands and feet, and hanged them by the pool in Hebron. But they took the head of Ishbosheth and buried it in the tomb of Abner in Hebron.
2 Samuel 5
1 Then all the tribes of Israel came to David at Hebron and spoke, saying, "Indeed we are your bone and your flesh.
2 Also, in time past, when Saul was king over us, you were the one who led Israel out and brought them in; and the Lord said to you, ’You shall shepherd My people Israel, and be ruler over Israel.’ "
3 Therefore all the elders of Israel came to the king at Hebron, and King David made a covenant with them at Hebron before the Lord. And they anointed David king over Israel.
4 David was thirty years old when he began to reign, and he reigned forty years.
5 In Hebron he reigned over Judah seven years and six months, and in Jerusalem he reigned thirty-three years over all Israel and Judah.
