The Psalms contain a significant number of laments, more than any other genre, constituting about one-third of the 150 psalms, roughly 50 in total. This makes laments a dominant feature of the Psalter, with more content dedicated to them than to many praise psalms. Individual laments are primarily found in the first book, Psalms 1-41, and are prominent in the early sections, while communal laments appear more in later parts, often addressing national or collective distress. As the Psalter progresses, laments decrease, and praise psalms become more prevalent, especially in Book Five. These psalms of lamentation serve as appeals to God for rescue from various distresses, such as physical illness, false accusations, persecution by enemies, warfare, or other personal and communal crises. Their prevalence reflects the reality of human struggle and suffering, bringing these difficult experiences into full view rather than denying them. Through these psalms, God encourages open acknowledgment and contemplation of trials, aiding in processing both emotional and intellectual responses to grief and trouble, offering at least 50 opportunities to learn from life's challenges. Laments typically follow a pattern of five elements: an invocation or cry to God, often with exalted titles; a description of the crisis or complaint; a petition or supplication for God to address the issue; a statement of confidence in God; and a concluding vow or expression of praise. While not always in strict order, and sometimes with elements repeated, omitted, or combined, these components are generally present. An example is Psalm 64, where the psalmist invokes God's help, describes the threat from enemies, petitions for protection, expresses confidence in God's intervention, and ends with praise for God's deliverance, transforming from woe to hope. Another example, Psalm 44, represents a communal lament, possibly written after a military defeat in David's time. It progresses through four sections reflecting the psalmist's thought process: recalling God's past deliverances, expressing perplexity at current abandonment, asserting faithfulness despite suffering, and ultimately trusting in God's future intervention. Despite lingering confusion and unresolved circumstances within the psalm, it ends on a note of raw faith, trusting in God's mercy and timing, providing a template for navigating severe, unresolved trials with enduring hope.

Psalms of lament are the most numerous genre in the book of Psalms. More than one third and as many as about sixty of the one hundred fifty psalms are laments or sad songs. Praise songs come quite a bit down the list even though they rank as the second most common type. Even in psalms of lament the mood turns toward praise at the end once the psalmist concludes that God remains God. Many psalms of lament appear because things are not always going well. The emotions of praise psalms stand as the opposite of the laments. Praise psalms form one end of the spectrum of ways to approach God. They emphasize joy instead of grief, positivity rather than dejection, and thankfulness instead of uncertainty. These positive attributes represent the proper response to God's faithfulness.

Laments containing imprecations, or curse prayers, form a distinct subset within the Psalms and represent authors under severe persecution or oppression calling for misfortune, disaster, or death to strike their enemies. These imprecations rarely constitute entire psalms; instead, they typically appear as a few verses—sometimes only one to three—embedded within larger psalms of lamentation. Psalms 5, 10, 11, 17, 35, 55, 58, 59, 69, 79, 83, 94, 109, 137, 139, and 140 contain such curses, with similar imprecations found in Jeremiah's prayers, Nehemiah's prayers, and Lamentations. Psalm 137 illustrates the pattern: after lamenting the exile in Babylon, the psalmist pronounces judgment on Edom and Babylon, declaring "happy shall he be who repays you as you have served us." This reflects a principle of reciprocal justice—what goes around comes around—rather than mere vindictiveness. Four foundational principles clarify why these curses appear legitimately in Scripture. First, imprecations are prayers directed to God, not actions taken by the psalmists themselves; the psalmists never seize vengeance personally but request that God act. Second, the seeming hatred expressed is rooted in genuine violations of justice and fairness—these are hyperbolic expressions of outrage against egregious, life-threatening wickedness, not petty grievances. Third, the imprecations call for God's justice to fall on enemies as a means of bringing mercy and relief to the suffering, essentially asking God to rebalance the scales of justice rather than empowering the oppressed to retaliate. Fourth, the covenant relationship between God and Israel underlies these prayers; Deuteronomy 29-30 establishes that disobedience brings covenant curses, but repentance leads God to place those same curses on Israel's enemies instead. Psalmists like David often stress their own obedience or repentance before invoking imprecations, effectively reminding God to fulfill His covenant promise to fight their battles. Psalm 83 (Asaph) exemplifies righteous imprecation, since the psalmist asks God to shame the enemies specifically "that they may seek Your name"—transforming vengeance into an opportunity for repentance. Psalm 5 shows the typical pattern: lament, brief imprecation, then blessing for the righteous. Psalm 109, containing twenty-four curses, demonstrates that David seeks justice and equity, not personal violence, explicitly leaving vengeance to God rather than executing it himself. Curses are not inherently evil, as demonstrated by Joshua's curse on Jericho and Jesus Christ's own curse on the fig tree, both serving as instructive, God-sanctioned acts. Jesus's teaching in Matthew 5:43-45, however, raises the standard under the New Covenant, commanding believers to love and pray for enemies rather than curse them. Thus imprecatory psalms remain spiritually useful chiefly as vehicles for processing righteous anger and frustration in submission to God's will, reminding believers that God will punish wickedness in His own time, even if that judgment awaits Christ's return, and teaching patience and trust in God's justice rather than personal vengeance.
