Consider Tyre, they too laugh at Jerusalem, saying "Aha!" (Ezek 26:2 NIV) They are glad for Jerusalem's fall at the hands of Nebuchadnezzar. They now have a little less competition. They think that because Jerusalem has fallen, they will now prosper even more. But, they will not be glad for long. God will send this same Nebuchadnezzar to ravage Tyre. They will no longer be the great city that they were.
Consider, again those whom you would laugh at and rejoice over when they fall because you might now have an advantage. Consider your boasting when you prevail over a friend or foe. Does God not hear? Will He come to their aid and take all that you thought you had won away?
God's Peace - Pr. J
