Shared ground
These verses present suffering on two fronts at once: public hostility and internal collapse. The speaker is shamed “all day” (v.8) and becomes a negative example others invoke (“use my name as a curse,” v.8). At the same time, grief affects basic life rhythms: food and drink are described in mourning terms (v.9). The speaker then states his own explanation for why this is happening—God’s “indignation” and “wrath” (v.10)—and sums up his condition as rapidly fading life (v.11).
Explicitly in the text, the speaker attributes his decline to God’s anger (v.10). The passage also clearly shows that social scorn and physical weakness can be intertwined, and that prayer in the Psalms can include unfiltered speech about feeling rejected by God.
Where interpretation differs
What it means to “use my name as a curse” (v.8). Some read this as opponents speaking against him (treating his name as something hateful). Others read it as opponents swearing by him—using his name in curse-formulas (“May you become like ___”), making him a byword.
How literal the “ashes” and “tears” are (v.9). Some take “eaten ashes” as a vivid way of saying grief has ruined appetite and daily life. Others think it alludes to actual mourning practices (sitting in ashes, ash getting into food), without requiring a literal diet of ash.
How direct the link is between suffering and God’s displeasure (v.10). Some treat the speaker’s explanation as broadly true: suffering here is God’s discipline or judgment. Others treat it more cautiously: the text records the speaker’s interpretation in distress without claiming that every similar experience is always caused by God’s anger.
Why the disagreement exists
The language is poetic and compressed, and it uses social customs (curse-phrases, mourning in ashes) that can be read more than one way. Also, the psalm reports the speaker’s reasoning (“because of your indignation”) inside a lament, which raises the question of whether the line is meant as a universal rule or as a personal, felt explanation within a crisis.
What this passage clearly contributes
It contributes a realistic picture of a person experiencing relentless public shame and private unraveling at the same time (vv.8–9), interpreting the crisis in Godward terms (v.10), and describing life as fragile and near its end (v.11). It also shows that biblical prayer can include the fear of being “thrown away” by God (v.10) without smoothing over that tension. See also Job 30:30–31 for similar bodily imagery of grief.
