(8-9) According to the number of the tribes. . . .--Every tribe was represented by a stone on either side Jordan. The two cairns represent a complete Israel in the wilderness, and a complete Israel in the promised land. "Thou shalt remember all the way that the Lord thy God led thee." "By the grace of God I am what I am."

4:1-9 The works of the Lord are so worthy of rememberance, and the heart of man is so prone to forget them, that various methods are needful to refresh our memories, for the glory of God, our advantage, and that of our children. God gave orders for preparing this memorial.And the children of Israel did so as Joshua commanded,.... That is, the twelve men taken out of the twelve tribes of Israel, and who were the representatives of them in this action:

and took up twelve stones out of the midst of Jordan, as the Lord spake unto Joshua, according to the number of the tribes of the children of Israel; they took the exact number, and out of the very place Joshua was ordered to direct them to do:

and carried them over with them unto the place where they lodged: which, as Josephus says (i), was fifty furlongs from Jordan, which was above six miles; so far they carried these stones on their shoulders:

and laid them down there; which afterwards were put in proper order by Joshua, or at least by his direction.
