'Harm' in the Bible

Then it happened on the seventh day that the child died. David’s servants were afraid to tell him that the child was dead, for they said, “While the child was still alive, we spoke to him and he would not listen to our voices. How then can we tell him the child is dead, since he might harm himself [or us]?”

And David said to Abishai [his nephew], “Now Sheba the son of Bichri will do us more harm than Absalom did. Take your lord’s servants and pursue him, so that he does not find fortified cities for himself and escape from our sight.”
