It may have something to do with Psalm 68

“1 May God arise, may his enemies be scattered; may his foes flee before him. 2 May you blow them away like smoke— as wax melts before the fire, may the wicked perish before God. 3 But may the righteous be glad and rejoice before God; may they be happy and joyful. 4 Sing to God, sing in praise of his name, extol him who rides on the clouds ; rejoice before him—his name is the LORD.”.........
