'Attacking' in the Bible

Now please pay attention closely! My whole family is attacking your humble servant! They're saying, "Turn over the one who attacked his brother and we'll put him to death in retribution for his brother, whose life he took. That way, we'll kill the heir also!' They're going to extinguish the only light left in my family, leaving my late husband neither an ongoing name nor a survivor on the face of the earth!"

When David saw the angel who had been attacking the people, he told the LORD, "Look, I'm the one who has sinned! I did the evil. These are only sheep! What did they do? Please, let your hand fall on me and on my household!"
