Why Did Israel Erect A Monument After Crossing The Jordan?

Joshua 4
Joel Webbon

“Some of the Israelites that passed over Jordan perhaps were so stupid, and so little affected with this great favour of God to them, that they felt no concern to have it remembered; while others, it may be, were so much affected with it, and had such deep impressions made upon them by it, that they thought there needed no memorial of it to be erected, the heart and tongue of every Israelite in every age would be a living lasting monument of it. But God, knowing their frame, and how apt they had been soon to forget his works, ordered an expedient for the keeping of this in remembrance to all generations, that those who could not, or would not, read the record of it in the sacred history, might come to the knowledge of it by the monument set up in remembrance of it.” -Matthew Henry
