For Pekah the son of Remaliah slew in Judah an hundred and twenty thousand in one day, which were all valiant men; because they had forsaken the LORD God of their fathers. A hundred and twenty thousand - It is very probable that there is a mistake in this number. It is hardly possible that a hundred and twenty thousand men could have been slain in one day; yet all the versions and MSS. agree in this number. The whole people seem to have been given up into the hands of their enemies.
