TSK · Genesis 2:23

Speak, I pray you, in the ears of all the men of Shechem, Whether [is] better for you, either that all the sons of Jerubbaal, [which are] threescore and ten persons, reign over you, or that one reign over you? remember also that I [am] your bone and your flesh.

And say ye to Amasa, [Art] thou not of my bone, and of my flesh? God do so to me, and more also, if thou be not captain of the host before me continually in the room of Joab.

So ought men to love their wives as their own bodies. He that loveth his wife loveth himself.
