TSK · Lamentations 3:65

But King Sihon of Heshbon was unwilling to allow us to pass near him because the LORD our God had made him obstinate and stubborn so that he might deliver him over to you this very day.

He loved to curse others, so those curses have come upon him. He had no desire to bless anyone, so he has experienced no blessings.

Let anyone who has no love for the Lord be accursed. Our Lord, come!
