Charles Ellicott Commentary Psalms 74:10-15

"How long, O God, shall the adversary reproach? Shall the enemy blaspheme thy name for ever? Why drawest thou back thy hand, even thy right hand? [Pluck it] out of thy bosom [and] consume [them]. Yet God is my King of old, Working salvation in the midst of the earth. Thou didst divide the sea by thy strength: Thou brakest the heads of the sea-monsters in the waters. Thou brakest the heads of leviathan in pieces; Thou gavest him to be food to the people inhabiting the wilderness. Thou didst cleave fountain and flood: Thou driedst up mighty rivers." — Psalms 74:10-15 (ASV)

In the true prophetic spirit, as Moses brought the cries of distress by reason of their bondage from the oppressed Israelites to God (Exodus 5:22), so this poet carries to the same God the pathos of this later cry, How long? how long? In answer, the deliverances of old rush into his mind. He recalls the right hand once stretched out to save (now thrust in inaction into the bosom), the wonders at the Red Sea, and all the long-continued providential guiding. Surely the same God will do the same wonders now!
