'Flesh' in the Bible

Then came all the tribes of Israel to David unto Hebron, and spake, saying, Behold, we are thy bone and thy flesh.

And he dealt among all the people, even among the whole multitude of Israel, as well to the women as men, to every one a cake of bread, and a good piece of flesh, and a flagon of wine. So all the people departed every one to his house.

Ye are my brethren, ye are my bones and my flesh: wherefore then are ye the last to bring back the king?

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.
