You formed my inward being

...You formed my inward being,
You knit me together in my mother's womb...
Your mysteries fill me with wonder!
More than I know myself do You know me;
my essence was not hidden from You,
When I was being formed in secret,
intricately fashioned from the elements of the earth...
~ Nan Merrill, "Psalm 139" in PSALMS FOR PRAYING
