Hushai‘s argument is that there was no chance of seizing David by surprise as Ahithophel suggested. There was sure to be sharp fighting, and the terror of the names of David, Joab, Abishai, Ittai, and their companions, would magnify the first few blows received into a victory, and Absalom‘s men would flee in panic.
