Psalm 99:6-8

6Moses and Aaron were among his priests, Samuel was among those who called on his name; they called on the LORD and he answered them.

7He spoke to them from the pillar of cloud; they kept his statutes and the decrees he gave them.

8LORD our God, you answered them; you were to Israel a forgiving God, though you punished their misdeeds. Or God, / an avenger of the wrongs done to them
