1 Chronicles 12:15
These are they that went over Jordan in the first month, when it had overflown all his banks; and they put to flight all them of the valleys, both toward the east, and toward the west. These are they that went over Jordan in the first month, when it had overflown all his banks; and they put to flight all them of the valleys, both toward the east, and toward the west.
1 Chronicles 12:15 is part of the parallel account of the events surrounding David's rise to the throne over all Israel. It belongs to the account of David's mighty men, the description of the mighty men from the tribes who gathered to David. That gathering was the assembly at Hebron where the tribes acknowledged David as king over all Israel. The assembly comprised about 350,000 fighting men and continued for three days as a festival.
The verse records that they went over Jordan in the first month, when it had overflowed all its banks. That crossing took place during the spring flood of the river. Those who crossed put to flight all them of the valleys, both toward the east and toward the west, routing the people in the surrounding valleys on both sides of the river and driving their enemies from them.
