Joshua 4:4-6

New Revised Standard Version, Anglicised Catholic Edition

⁴ Then Joshua summoned the twelve men from the Israelites, whom he had appointed, one from each tribe. ⁵ 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, ⁶ so that this may be a sign among you. When your children ask in time to come, “What do those stones mean to you?”
