Midrash sa Mga Awit 139:15: Midrash Tanchuma, Mekhilta DeRabbi Yishmael & Midrash Tehillim

This is explained in the tradition by David, king of Israel, as is said: My frame was not hidden from Thee, when I was made in secret and curiously wrought in the lowest parts of the earth (Ps. 139:15). This refers to the lowest portion of the mother’s womb.

The measure of flesh and blood — he cannot make a form from earth. But the Holy One Blessed be He does make a form from earth, viz. (Psalms 139:15) "I was wrought in secrecy, knit together in the recesses of the earth, etc."

"For there is no God but the Lord," said Hannah (Samuel 1:2). "There is none holy like the Lord, and there is none besides You; there is no Rock like our God" (1 Samuel 2:2). There is no artist like our God. This artist cannot paint with water, but the Lord is master of the waters, as it says, "Let the waters swarm" (Genesis 1:20). This artist is limited in darkness, but the Lord is master of darkness, as it says, "Who creates darkness" (Isaiah 45:7). This artist creates one shape from another shape and from many symbols of red, black, white, and green. The Lord forms man with one drop of white and one drop of red. This artist cannot create a shape all at once, but rather slowly, bit by bit, until it is finished. However, the Lord created it all at once, as it says, "For He who made everything is the Lord" (Jeremiah 10:16). Flesh and blood praises its own form, but the Lord's form praises Him. Flesh and blood cannot instill in it spirit, soul, entrails, and offspring, but the Holy One, blessed be He, forms shape and instills in it spirit, soul, entrails, and offspring, as it says, "Bless the Lord, O my soul" (Psalm 104:1). Therefore, we say, "There is no Rock besides our God."...
