Punishment for sins

2 Samuel 12 10 Now therefore the sword shall never depart from thine house; because thou hast despised me, and hast taken the wife of Uriah the Hittite to be thy wife.  -kjv 10 Now, therefore, the sword will never depart from your house, because you despised me and took the wife of Uriah the Hittite to be your own.’  -niv 10 Now therefore, the sword will never leave your house because you despised Me and took the wife of Uriah the Hittite to be your own wife.’  -hcsb David sinned against God by committing adultery with Bathsheba and plotted to had her husband, Uriah, killed. God punished David's sins. David's punishment included death to four of his sons. The first death was the first baby Bathsheba conceived owing to the adultery with David. He was still born. Then Absalom killed Amnon because he disgraced his sister Tamar. Absalom was later killed when he revolted against David. Lastly, Adonijah was killed by Solomon when he plotted against him when he was king. This happened after David was dead. Thus we see punishment for David from God started immediately after the adultery, extended throughout his life when his children were adults and even after death. However, David's life was spared owing to God's mercy and David's soul still entered heaven because he repented of his sins
