Charles Ellicott Commentary 1 Samuel 2:9

"He will keep the feet of his holy ones; But the wicked shall be put to silence in darkness; For by strength shall no man prevail." — 1 Samuel 2:9 (ASV)

He will keep the feet. —This was the comforting deduction Hannah drew from the circumstances of her life; this was the grave moral reflection the Spirit of the Lord instructed her to set down for the support and solace of all true servants of the Eternal in ages to come.

Since Jehovah of Israel governs the world, the righteous have nothing really to fear; it is only the wicked and rebellious who have reason to be afraid.

The Babylonian Talmud has the following comment on these words: “If any man has passed the greater part of his years without sin, he will sin no more. If a man has been able to resist the same temptation once or twice, he will sin no more; for it is said, He will keep the feet of his saints (1 Samuel 2:9).” —Treatise Yoma, fol. 38,Colossians 2:0.

By strength shall no man prevail. —The same thought is expressed very grandly by the prophet, Not by might, nor by power, but by my Spirit, saith the Lord of hosts (Zechariah 4:6). The Holy Ghost, in one of the sublime visions of St. Paul, taught the suffering apostle the same great truth, My grace is sufficient for thee: for my strength is made perfect in weakness (2 Corinthians 12:9).
