For you created my inmost being;
you knit me together in my mother’s womb.
I praise you because I am fearfully and wonderfully made;
your works are wonderful,
I know that full well.
It's interesting to think about the people in David's time knitting. I don't know the Hebrew word that David used for our English word, "knit," nor the history of knitting but I do know the intricacy and time involved in the process. Every piece is unique, even when following a pattern. Maybe the differences are minute and only noticed by the creator but each is one-of-a-kind and useful. God has a purpose for every individual He creates even if they have dropped stitches or uneven rows.
