Psalm 139:16
Thine eyes did see my substance, yet being unperfect; and in thy book all my members were written, which in continuance were fashioned, when as yet there was none of them.
Thine eyes did see my substance, yet being unperfect,.... The word {q} for "substance" signifies a bottom of yarn wound up, or any rude or unformed lump; and designs that conglomerated mass of matter separated in the womb, containing all the essentials of the human frame, but not yet distinguished or reduced into any form or order; yet, even when in this state, the eyes of the Lord see it and all its parts distinctly;
and in thy book all my members were written: which in continuance were fashioned, when as yet there was none of them; in the book of God's eternal mind, and designs, the plan of the human body was drawn, all the parts of it described, and their form, places, and uses fixed, even when as yet not one of them was in actual being; but in due time they are all exactly formed and fashioned according to the model of them in the mind of God; who has as perfect knowledge of them beforehand as if they were written down in a book before him, Or "in thy book are written all of them, what days they should be fashioned"; not only each of the members of the body were put down in this book, but each of the days in which they should be formed and come into order: "when" as yet there was "none of them"; none of those days, before they took place, even before all time; the Targum is,
"in the book of thy memory all my days are written, in the day the world was created, from the beginning that all creatures were created.''
