Psalms 139:13-14

The word "For" indicates that what follows explains what precedes. Since God creates people, He knows them intimately, and He is always with them. The idea of God creating David arose from Psalms 139:11-12. Forming as a potter and knitting as a weaver describe the gestation process figuratively (Psalms 139:13). "Thou" or "You" is again in the emphatic first position in the Hebrew text. David marveled at God’s amazing power in creating him by the embryonic process of fetal development.
