Psalm 139:13-14 (KJV)

13  For thou hast possessed my reins: thou hast covered me in my mother's womb.

14  I will praise thee; for I am fearfully and wonderfully made: marvellous are thy works; and that my soul knoweth right well.

Covered: To overspread the surface of a thing with another substance; to lay or set over; as to cover a table with a cloth, or a floor with a carpet. In some versions translated as knitted together.

God describing knitting our pre-existing spirit to our flesh at conception as per Kerr’s revelation.
