Under Gods Command
Proverbs 24:17-18 Do not gloat when your enemy falls; when he stumbles, do not let your heart rejoice, or the LORD will see and disapprove and turn his wrath away from him.
David, Solomon’s father, refused to gloat over the death of his lifelong enemy Saul. On the other hand, the nation of Edom rejoiced over Israel’s defeat and was punished by God for their attitude. To gloat over other’s misfortune is to make you the avenger and to put yourself in the place of God, who alone is the real judge of all the earth.
