"The LORD reigneth; let the people tremble: he sitteth between the cherubims; let the earth be moved. The LORD is great in Zion; and he is high above all the people. Let them praise thy great and terrible name; for it is holy. The king's strength also loveth judgment; thou dost establish equity, thou executest judgment and righteousness in Jacob. Exalt ye the LORD our God, and worship at his footstool; for he is holy. Moses and Aaron among his priests, and Samuel among them that call upon his name; they called upon the LORD, and he answered them. He spake unto them in the cloudy pillar: they kept his testimonies, and the ordinance that he gave them. Thou answeredst them, O LORD our God: thou wast a God that forgavest them, though thou tookest vengeance of their inventions. Exalt the LORD our God, and worship at his holy hill; for the LORD our God is holy." - Psalm 99
