Psalm 77 describes the speaker's initial state of deep distress and unanswered prayer. The text highlights their longing for God's help and questioning of divine favor and promises. However, it then shifts focus to the speaker recalling God's past miraculous deeds, particularly the redemption of Israel from Egypt and the parting of the Red Sea. This remembrance leads to a declaration of God's holiness and power, ultimately concluding with an affirmation of God's guidance for his people.
