Joshua 3:15

Jordan overfloweth all his banks - Rather “is full up to all his banks,” i. e. “brim-full.” This remark strikingly illustrates the suddenness and completeness, not less than the greatness, of the marvel. The Jordan River flows at the bottom of a deep valley, which descends to the water’s edge on either side in two, occasionally in three, terraces. Within the lowest of these the stream, ordinarily less than 100 feet wide in this lower part of its course, is confined. The margin is overgrown with a jungle of tamarisks and willows, which in the spring is reached by the rising waters (compare the figure in Jeremiah 49:19; Jeremiah 50:44); and the river, occasionally at least, fills the ravine which forms its proper bed to the brim. Its highest rise takes place about the time when Joshua had to cross it. By the middle of April the river cannot be forded; and, if passed at all, can only be so by swimming. This, however, was a hazardous feat (compare 1 Chronicles 12:15); and though no doubt performed by the two spies, was utterly out of the power of the mixed multitude that followed Joshua. The mere fact that the whole vast host crossed the stream of Jordan at this season, is no small proof of the miracle here recorded. No human agency then known and available could have transported them speedily and safely from bank to bank.
