Shared ground
Psalm 60:11–12 ends the poem with a tight movement from request to confidence. The speaker asks God for help “against the adversary,” because “the help of man is vain.” The psalm is not denying that people can act; it is saying that, in this crisis, human strength by itself is not dependable.
The confidence in verse 12 keeps God as the decisive agent. “Through God we shall do valiantly” holds together real human action and real dependence. The last line completes the thought: God will “tread down” the adversaries, a victory image that credits the outcome to God, not to human allies.
Where interpretation differs
One question is what counts as “the help of man.” Some read it as a rejection of outside military support (allies, reinforcements, strategy) as the ultimate hope. Others hear a broader claim: any merely human resource, even one’s own army, cannot secure the needed deliverance.
A second question is how to picture “tread down.” Some take it as strong poetry for decisive defeat. Others think it may echo literal battlefield language while still functioning poetically.
Why the disagreement exists
The verses are short and use broad terms (“man,” “adversary,” “tread down”). The psalm also balances two lines that can be weighed differently: “we shall do valiantly” (human participation) and “he…will tread down” (divine decisiveness). Readers decide how wide to make the contrast between human help and God’s help, and how concrete to imagine the victory imagery.
What this passage clearly contributes
Explicitly, the text claims (1) God is the proper one to ask for help against an active enemy, (2) merely human help fails as a final basis for confidence in this kind of threat, (3) the community expects courageous action “through God” (), and (4) God is the one who will bring the adversaries down.
By implication (without being spelled out as a rule for every situation), the ending models a way of speaking about conflict where human effort is real but not ultimate, and where the expected outcome is grounded in God’s action rather than in human capability alone.
