Deuteronomy 31:19-21

New Revised Standard Version, Anglicised

¹⁹ Now therefore write this song, and teach it to the Israelites; put it in their mouths, in order that this song may be a witness for me against the Israelites. ²⁰ For when I have brought them into the land flowing with milk and honey, which I promised on oath to their ancestors, and they have eaten their fill and grown fat, they will turn to other gods and serve them, despising me and breaking my covenant. ²¹ And when many terrible troubles come upon them, this song will confront them as a witness, because it will not be lost from the mouths of their descendants. For I know what they are inclined to do even now, before I have brought them into the land that I promised them on oath.’
