1 Samuel 2:9 - Wesley's Explanatory Notes

Feet — That is, the steps or paths, their counsels and actions; he will keep; that is, both uphold, that they may not fall into ruin; and direct and preserve from wandering, and from those fatal errors that wicked men daily run into. Silent — Shall be put to silence: they who used to open their mouths wide against heaven, and against the saints, shall be so confounded with the unexpected disappointment of all their hopes, and with God's glorious appearance and operations for his people, that they shall have their mouths quite stopped. Darkness — Both inward, in their own minds, not knowing what to say or do; and outward, in a stat e of deep distress. Prevail — Namely, against God, or against his saints, as the wicked were confident they should do, because of their great power, and wealth, and numbers.
