'Attack' in the Bible

David had said, "On that day {when we attack the Jebusites}, one must attack the lame and the blind, [those] who hate the soul of David, by [means of] the water supply." For thus the blind and the lame would say, "He cannot come into the house."

Then David said to the messenger, "Thus you shall say to Joab, '{Do not feel badly about this matter}; {now one and then another} the sword will devour. Intensify your attack on the city and overthrow it.'" And he encouraged him.

Then David said to all his servants who [were] with him in Jerusalem, "Get up and let us flee, for there will be no escape for us from Absalom! Hurry to go, otherwise he will come quickly and overtake us! And he will bring disaster on us and evil! He will attack the city with the edge of the sword!"
