He has lost connection to the head, from whom the whole body, supported and knit together by its joints and ligaments, grows as God causes it to grow.
KJV
And not holding the Head, from which all the body by joints and bands having nourishment ministered, and knit together, increaseth with the increase of God.
ASV
and not holding fast the Head, from whom all the body, being supplied and knit together through the joints and bands, increaseth with the increase of God.
