With another grand baby arriving in a few short weeks, these verses come to mind. We used them on the birth announcement for our fifth child. Verses 13 and 16 always cause a sense of awe when I read them. God formed us in our mother’s womb, and He knows the days He has for us. 

Psalm 139:13-16 New American Standard Bible (NASB)

¹³ For You formed my inward parts;
You wove me in my mother’s womb.
¹⁴ I will give thanks to You, for I am fearfully and wonderfully made;
Wonderful are Your works,
And my soul knows it very well.
¹⁵ My frame was not hidden from You,
When I was made in secret,
And skillfully wrought in the depths of the earth;
¹⁶ Your eyes have seen my unformed substance;
And in Your book were all written
The days that were ordained for me,
When as yet there was not one of them.
