Genesis 2:24 / John 17:21-23

Genesis 2:24

Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.

John 17:21-23

That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me. And the glory which thou gavest me I have given them; that they may be one, even as we are one: I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me.
