O LORD, You have searched me and known me!
You know when I sit down and when I rise up….
For You formed my inward parts; You knitted me together in my mother’s womb.
I praise You, for I am fearfully and wonderfully made.
Wonderful are Your works; my soul knows it very well.
My frame was not hidden from You, when I was being made in secret, intricately woven in the depths of the earth.
Your eyes saw my unformed substance; in Your book were written, every one of them,
the days that were formed for me, when as yet there was none of them.
How precious to me are Your thoughts, O God!

Psalm 139:1,2,13-17 (ESV)
