Forthwith Immediately. And when he sowed, some seeds fell by the way side, and the fowls came and devoured them up: some fell upon stony places, where they had not much earth: and FORTHWITH they sprung up, because they had no deepness of earth: and when the sun was up, they were scorched; and because they had no root, they withered away. (Mat 13,6)
