Deuteronomy 32:17-19

Revised Standard Version Catholic Edition

¹⁷ They sacrificed to demons which were no gods,
    to gods they had never known,
to new gods that had come in of late,
    whom your fathers had never dreaded.
¹⁸ You were unmindful of the Rock that begot^[a] you,
    and you forgot the God who gave you birth.
