Psalms 99:6-9

Moses and Aaron were among his priests, and Samuel was among his worshipers. They called to the LORD, and he answered them. He spoke to them from the pillar of cloud. They kept the rules and laws he gave them. LORD our God, you answered them. You showed them that you are a forgiving God, but you punished them for their wrongs. Praise the LORD our God, and worship at his holy mountain, because the LORD our God is holy.
