'Behind' in the Bible

I saw at night, and behold, a man was riding on a red horse, and he was standing among the myrtle trees which were in the ravine, with red, sorrel and white horses behind him.

“but I scattered them with a storm wind among all the nations whom they have not known. Thus the land is desolated behind them so that no one went back and forth, for they made the pleasant land desolate.”
