'My Own Flesh And Blood' in the Bible

Then David said to Abishai and all his servants, “Look, my own son, my own flesh and blood, intends to take my life—how much more now this Benjaminite! Leave him alone and let him curse me; the Lord has told him to.

You're my relatives! You're my own flesh and blood! So why are you the last to bring back the king?'

Then ask Amasa, "Aren't you my own flesh and blood? So may God deal with me, no matter how severely, if from this day forward you don't take Joab's place as commander of my army.'
