Ye are gone away (have turned aside) from mine ordinances. Disobedience was no new offence; they had always from early days been persistent in wickedness; and if the performance of God's sure promise was delayed, this was because they had not fulfilled the conditions on which rested its accomplishment.
Return: unto me, and I will return unto you (Zechariah 1:3, where see note). Man must cooperate with God's preventing grace, and then God gives him further grace unto repentance and amendment. Here, if the people followed the preaching of the prophets and obeyed the promptings of the Holy Spirit, God promises to bless and save them.
Wherein shall we return? Here is the Pharisaical spirit, as in Malachi 1:6, etc. They do not acknowledge their offence; they consider that they are righteous and need no repentance.
