Charles Ellicott Commentary Malachi 3:7

"From the days of your fathers ye have turned aside from mine ordinances, and have not kept them. Return unto me, and I will return unto you, saith Jehovah of hosts. But ye say, Wherein shall we return?" — Malachi 3:7 (ASV)

Even from ... fathers. — Throughout the whole course of their history they had been a people (Exodus 32:9 and following); and now, when exhorted to repent, they ask in feigned innocence:

Wherein shall we return? ... Return unto me ... unto you. — Compare Zechariah 1:3.
