'Bone' in the Bible

And all the tribes of Israel come unto David, to Hebron, and speak, saying, 'Lo, we are thy bone and thy flesh;

my brethren ye are, my bone and my flesh ye are, and why are ye last to bring back the king?

And to Amasa say ye, Art not thou my bone and my flesh? Thus doth God do to me, and thus He doth add, if thou art not head of the host before me all the days instead of Joab.'
