4:1 Spake - This was commanded before, Josh 3:12, and is here repeated with enlargement, as being now to be put in execution.
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.
