What does 1 Kings 2:33 mean?
Solomon had already told Benaiah that Joab needed to be executed to bring justice for Abner and Amasa's murders (2 Samuel 20:8–10) many years earlier. Now, though, he refers to David's own curse on Joab and his descendants after Joab killed Abner in cold blood:May it fall upon the head of Joab and upon all his father's house, and may the house of Joab never be without one who has a discharge or who is leprous or who holds a spindle or who falls by the sword or who lacks bread! -–2 Samuel 3:29Solomon concludes his message by adding that this is about more than just carrying out the Lord's justice against Joab for his crimes. It's also about removing any obstacle to the Lord's blessing on the descendants and throne of David to allow them to experience God's peace forever.
The bloodguilt lay on the line of David, who didn't condone the murders but also didn't punish Joab at the time. He left the job for the next king: Solomon (1 Kings 2:5–6). David did to Solomon what Saul did to David. Saul or his sons had killed some Gibeonites—non-Israelite servants. Saul never gave the Gibeonites justice. God sent a famine for three years until David asked God what was going on. God told him, and David asked the Gibeonites how he could atone for Saul's sin. The Gibeonites asked for seven of Saul's male descendants. Once the men were dead, God lifted the famine. (2 Samuel 21:1–9).
It's wise of Solomon to take care of the issue soon after he becomes king and before God curses the nation for allowing a murderer to maintain his authority.
