Shared ground
These closing lines present a “final word” the psalmist treats as settled: God has spoken, and the message has been truly heard and confirmed (v.11). The content is simple and weighty: power belongs to God (v.11), and loyal love belongs to the Lord (v.12). The ending also states that God “rewards” (repays) each person in line with what that person has done (v.12). Together, the passage ties God’s strength to God’s faithful love and to moral accountability.
The text’s claims are not framed as a private feeling but as a reliable verdict about reality: human power is not ultimate, and God’s character includes both steady love () and real evaluation of human actions.
Where interpretation differs
Two main questions come up.
First, “God has spoken once… twice have I heard” (v.11) can be taken either as (1) God speaking more than once, or (2) a poetic way to say the message is certain and fully confirmed in the speaker’s mind. Either way, the point in context is the firmness of the divine message and the speaker’s confident reception of it.
Second, “reward… according to his work” (v.12) can be heard as mainly positive (“God pays back with benefits”) or as broader repayment either way (good for good, and also consequences for wrongdoing). The verse itself does not spell out both sides, but “according to work” naturally supports the wider idea of fitting repayment.
Why the disagreement exists
The wording is compact and poetic. “Once… twice” is an idiom that can signal emphasis, but it also sounds like counting occurrences. And the English word “reward” can sound only positive, while the underlying idea of “repay” can include either favorable or unfavorable outcomes depending on the deeds.
What this passage clearly contributes
Explicitly, it summarizes Psalm 62’s main claims: God’s speech is dependable; ultimate power is God’s possession, not something humans can secure by force or status; and God’s loyal love is real and defining. It also explicitly connects God’s character to moral accounting: God gives to each person in line with what that person has done (v.12). As a closing, it frames the psalm’s trust in God as trust in a God who is both strong and faithfully committed, and whose rule includes meaningful evaluation of human conduct.
