Albert Barnes Commentary 1 Chronicles 12:15

"These are they that went over the Jordan in the first month, when it had overflowed all its banks; and they put to flight all them of the valleys, both toward the east, and toward the west." — 1 Chronicles 12:15 (ASV)

For the danger of this exploit, see the marginal reference note.

This passage (1 Chronicles 12:8–15) seems to be taken verbatim from an ancient source. The poetic expressions in 1 Chronicles 12:8 and 1 Chronicles 12:14 are especially unlike the usual style of our author.
