John Trapp on Psalms 44:9

Only this, it ſhould have been remembred that the Lords hand was not ſhortned — but their iniquities bad ſeparated between them and their God, Iſa. 59.1,Niceph. l. 11. c. 40. 2. That noble General Trajan told Valens the Arrian Emperour, that by warring againſt God, hee had abandoned the Victory, and ſent it to the enemies.
