'Joined' in the Bible

So that their hearts may be comforted, and that being joined together in love, they may come to the full wealth of the certain knowledge of the secret of God, even Christ,

And not joined to the Head, from whom all the body, being given strength and kept together through its joins and bands, has its growth with the increase of God.

And more than all, have love; the only way in which you may be completely joined together.
