19 Your own wickedness will bring about your punishment. Your unfaithful acts will bring down discipline on you. Know, then, and realize how utterly harmful it was for you to reject me, the Lord your God, to show no respect for me,” says the Sovereign Lord of Heaven’s Armies.

Darby

19 Thine own wickedness chastiseth thee, and thy backslidings reprove thee: know then and see that it is an evil thing and bitter that thou hast forsaken Jehovah thy God, and that my fear is not in thee, saith the Lord, Jehovah of hosts.

KJV

19 Thine own wickedness shall correct thee, and thy backslidings shall reprove thee: know therefore and see that [it is] an evil [thing] and bitter, that thou hast forsaken the LORD thy God, and that my fear [is] not in thee, saith the Lord GOD of hosts.
