Passage
Therefore I swore in my wrath, “They won’t enter into my rest.”
Therefore I swore in my wrath, “They won’t enter into my rest.”
Psalms 95:9 when your fathers tempted me, tested me, and saw my work.
Psalms 95:10 Forty long years I was grieved with that generation, and said, “It is a people that errs in their heart. They have not known my ways.”
Psalms 95:11 Therefore I swore in my wrath, “They won’t enter into my rest.”
The verse centers on "therefore", "swore", "wrath", "enter", and "rest". It is saying that the verse draws attention to "therefore" and "swore", so its meaning should be read from those terms before moving to application.
The prior verse says "Forty long years I was grieved with...", giving immediate footing for "therefore" and "swore". In Psalms context, the local focus is worship, trust, the LORD's kingship, and covenant mercy.
A plain takeaway is to answer the verse's own emphasis on "therefore" and "swore" with trust shaped by these words, not by a vague optimism outside the passage.
