'Overthrow' in the Bible

the princes of the Ammonites said to Hanun their lord, “Do you think that David is honoring your father because he has sent consolers to you? Has David not sent his servants to you in order to search the city, to spy it out and overthrow it?”

Then David said to the messenger, “Thus you shall say to Joab, ‘Do not let this thing displease you, for the sword devours one as well as another; make your battle against the city stronger and overthrow it’; and so encourage him.”
