The Levites have left me and kept my law.
In the question: God is omnipotent, and He is the One who prefers that the people of Israel keep the Torah even if they have abandoned it. He has perfected the value of the Torah's consideration. Or in the question: A teacher says this about his wayward disciples.
("It is written (Jeremiah 16) And they have forsaken me and have not kept my law, the Levites have forsaken me and have kept my law, from the time that they were engaged in it, the light in it was returning to the best, Rav Huna said of the Torah, despite its name, that from its nameless nature came its name" - Ikha Rava (Vilna) Openings)
