+Psalm 99The King Is Holy
+
+1. The Lord reigns! Let the peoples tremble.
+He is enthroned between the cherubim.
+Let the earth quake.
+
+2. The Lord is great in Zion;
+he is exalted above all the peoples.
+
+3. Let them praise your great
+and awe-inspiring name.
+He is holy.
+
+4. The mighty King loves justice.
+You have established fairness;
+you have administered justice
+and righteousness in Jacob.
+
+5. Exalt the Lord our God;
+bow in worship at his footstool.
+He is holy.
+
+6. Moses and Aaron were among his priests;
+Samuel also was among those calling on his name.
+
+They called to the Lord 
+and he answered them.
+
+
+7. He spoke to them in a pillar of cloud;
+they kept his decrees and the statutes he gave them.
+
+8. Lord our God, you answered them.
+
+You were a forgiving God to them,
+but an avenger of their sinful actions.
+
+9. Exalt the Lord our God;
+bow in worship at his holy mountain,
+for the Lord our God is holy.
