What does the Bible say about the Sixth Commandment?

The Sixth Commandment, which states 'Thou shalt not kill,' extends far beyond the act of physical murder. It addresses the heart's attitudes toward others, indicating that harboring anger or hatred is equally serious in God's eyes. As noted in 1 John 3:17, 'Whosoever hateth his brother is a murderer,' emphasizing that God's commandment is spiritual and far-reaching. Paul acknowledges in Romans 7:14 that the law is spiritual, revealing our sinful nature and the broad scope of its application, which includes even our thoughts and feelings toward others, such as jealousy and disdain.
