The provision that was made at that time to preserve the memorial of it, by twelve stones set up in Jordan (Jos 4:9) and other twelve stones taken up out of Jordan (Jos 4:1-8). II. The march of the people through Jordan's channel, the two tribes first, then all the people, and the priests that bore the ark last (Jos 4:10-14). III. The closing of the waters again upon their coming up with the ark (Jos 4:15-19). IV. The erecting of the monument in Gilgal, to preserve the remembrance of this work of wonder to posterity (Jos 4:20-24).
