1 Chronicles 12:15

These are they that went over Jordan, &c. Namely, in Saul's time, when, it seems, the enemies of the Israelites had made an inroad, and done some mischiefs to the Israelites beyond Jordan, to whose help these persons then came. When it had overflowed all its banks As it commonly did about that time. Probably these, being men of great courage and dexterity, swam over Jordan, at the time here specified, through their ardent desire to help their brethren, and to fight with their enemies. And they put to flight all them of the valleys The people that lived in the valleys or deserts beyond Jordan, who, it seems, when Saul was engaged against the Philistines, took that advantage to fall upon the Israelites beyond Jordan. Both toward the east and toward the west Both the people that lived more eastward and remote from Jordan, and those that lived more westward and nearer to it.
