Albert Barnes Commentary Joshua 3:1

"And Joshua rose up early in the morning; and they removed from Shittim, and came to the Jordan, he and all the children of Israel; and they lodged there before they passed over." — Joshua 3:1 (ASV)

“The acacia groves” (Exodus 25:5 note) of Shittim on both sides of Jordan line the upper terraces of the valley (compare 2 Kings 6:4). They would be in this part at some six miles distance from the river itself.
