Matthew Henry on Joshua 4:1-9
We may well imagine how busy Joshua and all the men of war were while they were passing over Jordan, when besides their own marching into an enemy's country, and in the face of the enemy, which could not but occasion them many thoughts of hear, they had their wives, and children, and families, their cattle, and tents, and all their effects, bag and baggage, to convey by this strange and untrodden path, which we must suppose either very muddy or very stony, troublesome to the weak and frightful to the timorous, the descent to the bottom of the river and the ascent out of it steep, so that every man must needs have his head full of care and his hands full of business, and Joshua more than any…

(g) Sept. "eras", Pagninus, Montanus.
