Albert Barnes Commentary Psalms 34:20

"He keepeth all his bones: Not one of them is broken." — Psalms 34:20 (ASV)

He keepeth all his bones—That is, he preserves or guards the righteous.

Not one of them is broken—Perhaps there is a direct and immediate allusion here to what the psalmist had himself experienced. In his dangers God had preserved him, so that he had escaped without a broken bone.

But the statement is more general and is designed to convey a truth regarding the usual and proper effect of religion, or to denote the advantage concerning personal safety in the dangers of this life, derived from religion. The language is of a general character, such as often occurs in the Scriptures, and it should, in all fairness, be so construed.

It cannot mean that the bones of a righteous man are never broken, or that the fact that a man has a broken bone proves that he is not righteous; but it means that, as a general principle, religion contributes to safety, or that the righteous are under the protection of God. Compare Matthew 10:30-31. Nothing more can be demanded in the fair interpretation of the language than this.
