Psalms 139:16

¹⁴ I praise You, for I am fearfully and wonderfully made. Marvelous are Your works, and I know this very well.

¹⁵ My frame was not hidden from You when I was made in secret, when I was woven together in the depths of the earth.

Your eyes saw my unformed body; all my days were written in Your book and ordained for me before one of them came to be.

¹⁷ How precious to me are Your thoughts, O God, how vast is their sum!

¹⁸ If I were to count them, they would outnumber the grains of sand; and when I awake, I am still with You.

Do read the surrounding verses too, because the context often says more than a single verse.
