Psalms 139:15

My substance; or, My bone, as the LXX. and others render the word. And bone may be here taken collectively for bones, as is usual in such words, or for the whole fabric of the bones And the bones may be very fitly mentioned here, because they are inward and invisible, as being covered with skin, and flesh, and sinews. Or the bones may be put synecdochically for the whole body, as being the most substantial part of it, as they are Psalms 35:10. In secret; in the dark vault of my mother's womb. Curiously wrought, Heb. embroidered; exquisitely composed of bones, and muscles, and sinews, and veins, and arteries, and other parts, all framed with such wonderful skill, that even heathens, upon the contemplation of all the parts of man's body, and how excellently they were framed, both for beauty and use, have broken forth into pangs of admiration and adoration of the Creator of man, as Galen particularly did. In the lowest parts of the earth; or, as it were in the lowest parts of the earth. So there is only an ellipsis of the note of similitude, which is very frequent in Scripture, as hath been often said and proved. In a place as secret and remote from human eyes as the lowest parts of the earth are, to wit, in my mother's womb. And so what is said in the former clause is repeated in this in other words.
