Obadiah 1:12-13

But do not gloat over the day of your brother in the day of his misfortune; do not rejoice over the people of Judah in the day of their ruin; do not boast in the day of distress. Do not enter the gate of my people in the day of their calamity; do not gloat over his disaster in the day of his calamity; do not loot his wealth in the day of his calamity.
