Gave them leave. Compare the experience of Job (Job 1:12; 2:6); the proposal that brought injury to Job was made by the devil, and God simply consented to it, yet overruled all for the benefit and encouragement of Christians down through the ages.
Down a steep place. Literally, “down the precipice.” A short distance south of the village of Kursi, thought to be the ancient Gergesa (see on v. 1), there is a steep bluff, where the hills come down close to the water’s edge, the only place on the entire coast where this is true. The declivity is so steep that it might be called a cliff, though not of the overhanging type. At the foot of this precipice the beach is so narrow that the swine could not possibly have halted their headlong race.
Choked. Gr. pnigo, “to choke,” or “to strangle”; used here in the sense of “to be drowned.”
