13 For You1 formed my inward parts; You covered me in my mother’s womb.
14 I will praise You, for1 I am fearfully and wonderfully made; Marvelous are Your works, And that my soul knows very well.
15aMy1 frame was not hidden from You, When I was made in secret, And skillfully wrought in the lowest parts of the earth.
16 Your eyes saw my substance, being yet unformed. And in Your book they all were written, The days fashioned for me, When asyettherewere none of them.
17aHow precious also are Your thoughts to me, O God! How great is the sum of them!
18If I should count them, they would be more in number than the sand; When I awake, I am still with You.
19 Oh, that You would aslay the wicked, O God! bDepart from me, therefore, you1 bloodthirsty men.
20 For they aspeak against You wickedly; 1Your enemies take Yourname in vain.
The psalmist gives God credit for preparing him in the womb. He uses the personal pronoun "me" to refer to himself while still in the womb, and the Hebrew word for embryo appears as "substance, being yet unformed" (verse 16).
