Deuteronomy 31:18-20

New Revised Standard Version Catholic Edition

¹⁸ On that day I will surely hide my face on account of all the evil they have done by turning to other gods. 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.
