פירוש על בראשית 31:21

ויברח, usually the word בריחה, flight, means that someone departs without being pursued. The flight is inspired by fear of damage and harm not imminent. When the word ניסה is used to describe flight, this describes people fleeing from pursuers, out of fear from immediate damage and harm.

ויברח...את הנהר, the river Euphrates.
