'Ligaments' in the Bible

From Him the whole body [the church, in all its various parts], joined and knitted firmly together by what every joint supplies, when each part is working properly, causes the body to grow and mature, building itself up in [unselfish] love.

and not holding fast to the head [of the body, Jesus Christ], from whom the entire body, supplied and knit together by its joints and ligaments, grows with the growth [that can come only] from God.
