c. 400 · Augustine of Hippo, On the Catechising of the Uninstructed (De catechizandis rudibus) 21.37
On the subject of these two cities, which have been running their courses, mingling the one with the other, through all the changes of time from the beginning of the human race, and which shall so move on together until the end of the world, when they are destined to be separated at the last judgment, we have spoken already a little ago. That captivity, then, of the city of Jerusalem, and the people thus carried into Babylonia in bondage, were ordained so to proceed by the Lord, by the voice of Jeremiah, a prophet of that time. And there appeared kings of Babylon, under whom they were in slavery, who on occasion of the captivity of this people were so wrought upon by certain miracles that they came to know the one true God who founded universal creation, and worshipped Him, and commanded that He should be worshipped. Moreover the people were ordered both to pray for those by whom they were detained in captivity, and in their peace to hope for peace, to the effect that they should beget children, and build houses, and plant gardens and vineyards.
