Joshua 4:1-7, Psalm 78:1-8, Philippians 4:9 (New Revised Standard Version)
Joshua 4:1-7When the entire nation had finished crossing over the Jordan, the Lord said to Joshua: "Select twelve men from the people, one from each tribe, and command them, "Take twelve stones from here out of the middle of the Jordan, from the place where the priests' feet stood, carry them over with you, and lay them down in the place where you camp tonight.' " Then Joshua summoned the twelve men from the Israelites, whom he had appointed, one from each tribe. Joshua said to them, "Pass on before the ark of the Lord your God into the middle of the Jordan, and each of you take up a stone on his shoulder, one for each of the tribes of the Israelites, so that this may be a sign among you. When your children ask in time to come, "What do those stones mean to you?' then you shall tell them that the waters of the Jordan were cut off in front of the ark of the covenant of the Lord. When it crossed over the Jordan, the waters of the Jordan were cut off. So these stones shall be to the Israelites a memorial forever."
Psalm 78:1-8Give ear, O my people, to my teaching; incline your ears to the words of my mouth. I will open my mouth in a parable; I will utter dark sayings from of old, things that we have heard and known, that our ancestors have told us. We will not hide them from their children; we will tell to the coming generation the glorious deeds of the Lord, and his might, and the wonders that he has done. He established a decree in Jacob, and appointed a law in Israel, which he commanded our ancestors to teach to their children; that the next generation might know them, the children yet unborn, and rise up and tell them to their children, so that they should set their hope in God, and not forget the works of God, but keep his commandments; and that they should not be like their ancestors, a stubborn and rebellious generation, a generation whose heart was not steadfast, whose spirit was not faithful to God.
Philippians 4:9Keep on doing the things that you have learned and received and heard and seen in me, and the God of peace will be with you.
