Psalms 99:6-9

Moses and Aaron were his priests, Samuel among those who prayed to him. They prayed to GOD and he answered them; He spoke from the pillar of cloud. And they did what he said; they kept the law he gave them. And then GOD, our God, answered them (But you were never soft on their sins). Lift high GOD, our God; worship at his holy mountain. Holy. Yes, holy is GOD our God.
