New Defender's Study Bible Notes
139:16 unperfect. This “substance yet being unperfect” is one word in the Hebrew, meaning simply “embryo.” God is watching over each embryonic human being from the moment of conception. There is never a time when it is “recapitulating” its imaginary evolutionary ancestry, as the so-called “pro-choice” people seem to think. The baby is “unperfect,” not “imperfect,” until it is ready for delivery, but it is always truly human, with an eternal soul.
139:16 continuance. “In continuance” is the same as “days” in Hebrew. That is, God was overseeing the development of all the days of the life, as well as the substance of the body.
139:16 fashioned. The embryo is being “fashioned” in a way analogous to the way in which God “formed” (same word) the body of Adam from the dust of the earth (Genesis 2:7).
