'Loss' in the Bible

so David told himself, "I will be loyal to Nahash's son Hanun, since in his loyalty his father showed gracious love to me." So David sent a delegation to Hanun to console him about his loss of his father.

She replied, “Please, may the king invoke the Lord your God, so that the avenger of blood will not increase the loss, and they will not eliminate my son!”“As the Lord lives,” he vowed, “not a hair of your son will fall to the ground.”

And David said to all his servants who were with him at Jerusalem, Come, let us go in flight, or not one of us will be safe from Absalom: let us go without loss of time, or he will overtake us quickly and send evil on us, and put the town to the sword.
