'Flesh' in the Bible

After this, all of the tribes of Israel assembled with David at Hebron and declared, "Look, we're your own flesh and blood!

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.'
