Another interpretation: The precepts of the LORD are straightforward (Psalm 19:9) — Taught Ḥizkiyah son of Ḥiyyah, these are words of Torah, which are a crown for the head, as it is said For a graceful wreath are they on your head, a necklace on your throat. (Proverbs 1:9). A remedy for the heart — making the heart rejoice. A salve for the eyes — The commandment of the LORD is clear, illuminating the eyes.
An elixir for plague — Cure for your gut it will be (Proverbs 3:8). And a potion for the intestines — and a potion for your innards. (ibid.) And the number of swallowings is 248 organs — and to all his flesh it heals. (Proverbs 4:24)....ALTERNATIVE translation...: Another interpretation of "פקודי ה' ישרים" is given by Rabbi Hizkiyah bar Hayya. He said that these are the words of the Torah that are a crown for the head, as it is written, "for they shall be a garland of grace to your head and a necklace around your neck" (Proverbs 1:9).
They are balm for the heart, and they give joy to the soul. The commandments of the Lord are clear and enlighten the eyes. They are a remedy for the wound, as it is written, "Heal me, O Lord, and I shall be healed; save me, and I shall be saved, for you are my praise" (Jeremiah 17:14). They are a tonic for the stomach and give strength to the bones, as it is written, "It will be health to your flesh and refreshment to your bones" (Proverbs 3:8).
And how do we know that they penetrate to the two hundred and forty-eight organs and heal the whole body? As it is written, "For they are life to those who find them and healing to all their flesh" (Proverbs 4:22).
