Psalm 83
Keep not thou silence, O God: hold not thy peace, and be not still, O God. For, lo, thine enemies make a tumult: and they that hate thee have lifted up the head. They have taken crafty counsel against thy people, and consulted against thy hidden ones. They have said, Come, and let us cut them off from being a nation; that the name of Israel may be no more in remembrance. For they have consulted together with one consent: they are confederate against thee.my God, make them like a wheel; as the stubble before the wind... My God, make them like a wheel; as the stubble before the wind. As the fire burneth a wood, and as the flame setteth the mountains on fire; So persecute them with thy tempest, and make them afraid with thy storm. Fill their faces with shame; that they may seek thy name, O LORD.
