'My Bone and My Flesh' in the Bible

And Laban said to him, Truly, you are my bone and my flesh. And he kept Jacob with him for the space of a month.

You are my brothers, my bone and my flesh; why are you the last to get the king back again?

And say to Amasa, Are you not my bone and my flesh? May God's punishment be on me, if I do not make you chief of the army before me at all times in place of Joab!
