'Smitten' in the Bible

When thy people Israel are smitten down before the enemy, because they have sinned against thee; if they turn again to thee, and confess thy name, and pray and make supplication unto thee in this house:

For it came to pass, when David was in Edom, and Joab the captain of the host was gone up to bury the slain, and had smitten every male in Edom;

And the people that were encamped heard say, Zimri hath conspired, and hath also smitten the king: wherefore all Israel made Omri, the captain of the host, king over Israel that day in the camp.
