'Behind' in the Bible

I saw by night, and behold a man riding upon a red horse, and he stood among the myrtle trees that were in the bottom; and behind him were there red horses, speckled, and white.

“I scattered them with a windstorm over all the nations that had not known them, and the land was left desolate behind them, with no one coming or going. They turned a pleasant land into a desolation.”
