Charles Ellicott Commentary Deuteronomy 32:20

"And he said, I will hide my face from them, I will see what their end shall be: For they are a very perverse generation, Children in whom is no faithfulness." — Deuteronomy 32:20 (ASV)

A very perverse generation. —Literally, a generation of perversities.

Children in whom there is no faith. —Literally, children! — there is no relying on them. (Compare to Deuteronomy 5:5.) Faith is not used in the sense of "belief" or "confidence," but as in the expression to "keep faith," or to "break faith," children who will not keep faith with anyone.
