Cherubim are mighty angels that comprise one of several ranks of angels. (For more on angels, see the note on Psa 91:11.)
Psalms 99:3
Everyone should praise God's great and awesome name because his name points to his divine nature, his personage, and his reputation. But the name of God is often used so carelessly in conversation that we have lost sight of its holiness. How easy it is to treat God lightly in everyday life. If you claim him as your Father, live worthy of the family name. Respect God's name and give him praise by both your words and your life.
Psalms 99:5
God's holiness is terribly frightening for sinners, but a wonderful comfort for believers. God is morally perfect and is set apart from people and sin. He has no weaknesses or shortcomings. For sinners, this is frightening because all their inadequacies and evil are exposed by the light of God's holiness. God cannot tolerate, ignore, or excuse sin. For believers, God's holiness gives comfort because, as we worship him, we are lifted from the mire of sin. As we believe in him and humble ourselves before him, we are made holy.
Psalms 99:6
The Bible records several instances where Moses, Aaron, and Samuel cried out to God for help (Exo 15:25; Exo 17:4; Num 11:11-15; Num 12:13; Num 14:13; Num 16:44-48; 1Sa 7:5, 1Sa 7:9; 1Sa 15:11).
