The apex shows the twelve stones (one for each tribe of the children of Israel) taken up out of the midst of Jordan, and set up as a memorial to God drying up the waters until the people had passed over into Canaan. On the scroll are the words of Joshua: "Be thou strong and very courageous."

The figure of Joshua is that of a great leader, who, having brought the children of Israel into the Promised Land, told them: "I have given you a land for which ye did not labour, and cities which ye built not, and ye dwell in them; of the vineyards and oliveyards which ye planted not do ye eat" Joshua 24).

The base section shows the return of the spies sent by Joshua to spy out the land. They bring with them evidence of its prosperity and the fruitfulness of its fields.
