Psalm 139:16 in the King James Version
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.
Context
15 My frame wasn’t hidden from you, when I was made in secret, woven together in the depths of the earth.
16 Your eyes saw my body. In your book they were all written, the days that were ordained for me, when as yet there were none of them.
17 How precious to me are your thoughts, God! How vast is their sum!
