'Life' in the Bible

because my father fought on your behalf, throwing away all concern for his own life, and delivered you from Midian's domination.

When I saw that you wouldn't be delivering me, I took my own life in my hands, crossed over to fight the Ammonites, and the LORD gave them into my control. So why have you come here today to fight me?"

The descendants of Dan answered him, "You had better not talk to us about this, or else these bad guys here will attack you. You will lose your life, along with the lives of your whole household."
