tell those whitewashing the wall that it will fall. Rain will come in torrents, I will send hailstones plunging down, and a windstorm will burst forth.
KJV
Say unto them which daub [it] with untempered [morter], that it shall fall: there shall be an overflowing shower; and ye, O great hailstones, shall fall; and a stormy wind shall rend [it].
ASV
say unto them that daub it with untempered mortar, that it shall fall: there shall be an overflowing shower; and ye, O great hailstones, shall fall; and a stormy wind shall rend it.
