41 When all the people had crossed the Jordan, the Lord said to Joshua, 2 "Now choose twelve men, one from each tribe. 3 Tell them, 'Take twelve stones from the very place where the priests are standing in the middle of the Jordan. Carry them out and pile them up at the place where you will camp tonight.'" 4 So Joshua called together the twelve men he had chosen-one from each of the tribes of Israel. 5 He told them, "Go into the middle of the Jordan, in front of the Ark of the Lord your God. Each of you must pick up one stone and carry it out on your shoulder-twelve stones in all, one for each of the twelve tribes of Israel. 6 We will use these stones to build a memorial. In the future your children will ask you, 'What do these stones mean?' 7 Then you can tell them, 'They remind us that the Jordan River stopped flowing when the Ark of the Lord 's Covenant went across.' These stones will stand as a memorial among the people of Israel forever."

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.
