Thank you! David acknowledges it in Ps 139:

For thou hast possessed my reins: thou hast covered me in my mother's womb. Psa 139:14

I will praise thee; for I am fearfully and wonderfully made: marvellous are thy works; and that my soul knoweth right well. Psa 139:15

My substance was not hid from thee, when I was made in secret, and curiously wrought in the lowest parts of the earth. Psa 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.
