But he that sinneth against me wrongeth his own soul: all they that hate me love death.

When you read the whole chapter (the context), you see that the one speaking is wisdom, which the Bible defines as the ability to apply God's
Word to our daily lives. The New Testament defines wisdom as Jesus, who enables us to use the Bible correctly for our lives (1 Corinthians 1:28-31):
1Co 1:28 God chose what is low and despised in the world, even things that are not, to bring to nothing things that are,
1Co 1:29 so that no human being might boast in the presence of God.
1Co 1:30 And because of him you are in
Christ Jesus, who became to us wisdom from God, righteousness and sanctification and redemption,
1Co 1:31 so that, as it is written, “Let the one who boasts, boast in the Lord.”
