On the danger of the exploit, see the marginal reference note.
This passage 1-Chronicles 12:8-15 seems to be taken verbatim from an ancient source, the poetical expressions in 1-Chronicles 12:8, 1-Chronicles 12:14, being especially unlike the usual style of our author.

In the first month - Perhaps this was the month Nisan, which answers to a part of our March and April. This was probably before the snows on the mountains were melted, just as Jordan began to overflow its banks; or if we allow that it had already overflowed its banks, it made their attempt more hazardous, and afforded additional proof of their heroism.

These [are] they that went over Jordan in the (d) 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.
(d) Which the Hebrews called Nisan, or Abib, containing half March and half April, when Jordan was wont to overflow its banks, read (Joshua 3:15).

These are they that went over Jordan in the first month,.... The month Nisan or Ab; as they must come over Jordan to come to David, since they dwelt on the other side of it:
when it had overflown all its banks; as it did at this time of the year, see Joshua 3:15 which is observed to show both the time of the year when they came over, and their zeal and ardour to assist David, and their boldness and intrepidity; fearless of danger, they threw themselves into Jordan, and swam over it, in all probability when the waters of it were so deep they could not ford it, and so rapid that they were in danger of being carried away with them:
and they put to flight all them of the valleys, both towards the east, and towards the west; who dwelt in the valleys, or plains of Jordan east and west; who seeing a number of men come over, took them for enemies, and fled, so Kimchi; or, as others think, these were the Philistines, who, on the defeat of Saul, took possession of the cities of Israel, in the valleys forsaken by them, 1-Samuel 31:7 or rather these were the Moabites or Arabs, who made incursions into the land of Israel for prey, the Gadites met with, when they came over Jordan.

These are they that went over Jordan in the first month--that is, in spring, when the swollen river generally fills up the banks of its channel (see on Joshua 3:14; Joshua 4:19; Joshua 5:10).
they put to flight all them of the valleys--This was probably done at the time of their separating themselves and their purpose being discovered, they had to cut their passage through the opposing adherents of Saul, both on the eastern and western banks. The impossibility of taking the fords at such a time, and the violent rapidity of the current, make this crossing of the Jordan--in whatever way these Gadites accomplished it--a remarkable feat.
