The shared event is called a grievous feature; human inner life is troubled
The speaker labels it an “evil” (a painful, disturbing reality) that, in what is done “under the sun,” one event comes to all. He then adds an observation about the living: human hearts are full of evil, and madness is present while they live. The sequence ends bluntly—after life, “they go to the dead”—reinforcing death as the common destination that frames his complaint.
Shared ground
Ecclesiastes 9:1–3 holds two claims together. First, the speaker says the righteous and the wise, along with what they do, are “in the hand of God” (v.1). That is an explicit statement of God’s control or oversight.
Second, the speaker says humans still cannot read outcomes from what they can see: “a person doesn’t know” what lies ahead (v.1). And, in the most visible sense, “all things come alike” because “one event” comes to every category of person (vv.2–3). The passage presents death as the shared destination (v.3).
Where interpretation differs (only where needed)
What “love or hatred” refers to (v.1). Some read it mainly as God’s attitude: people cannot tell from circumstances whether God approves or disapproves of them. Others read it mainly as the human experience of life: people cannot tell whether what’s coming will feel like favor or opposition (from others, or from life’s events), even though God holds all.
What the “one event” is (vv.2–3). Many take it as death specifically, since v.3 ends with “after that they go to the dead.” Others think it includes any decisive fate that levels distinctions (especially death, but also the fact that life’s major turns do not track moral categories in a predictable way).
How to understand “evil” (v.3). Some take “evil” as moral evil being described in the world. Others take it as a painful tragedy: a disturbing feature of life “under the sun,” not a claim that the event itself is morally wrong.
Why the disagreement exists
The key terms are broad and the passage is observational rather than analytical. “Love/hate” can name either divine stance or lived experience, and “one event” could be narrowed by v.3’s reference to death or kept wider by v.2’s sweeping “all things come alike.” Also, “evil” can mean moral wrongdoing or a grievous reality, and the immediate context uses it to evaluate what happens in ordinary human life.
What this passage clearly contributes
The text explicitly teaches that God’s sovereignty (“in God’s hand,” v.1) does not make life predictable from the outside. Present conditions are not a reliable guide to what is coming (v.1). It also explicitly stresses that mortality is a shared outcome across moral, social, and ritual categories (vv.2–3). Finally, it adds an unflattering observation about the human interior: people often carry moral disorder and irrationality through life until death (v.3), which strengthens the sense that the world is not neatly sorted by visible merit or visible outcomes.
