TSK · Lamentations 3:65

But Sihon king of Heshbon would not let us pass by him; for Yahweh your God hardened his spirit, and made his heart obstinate, that he might deliver him into your hand, as at this day.

Yes, he loved cursing, and it came to him. He didn't delight in blessing, and it was far from him.

If any man doesn't love the Lord Jesus Christ, let him be accursed. Come, Lord!
