Jeremiah 3:22 - Matthew Poole's English Annotations on the Holy Bible

Return, viz. repent for sin and from sin. Here God calls upon them, and invites them to consider whither they are going, and to hearken unto the voice of his ministers, Hosea 14:1 Acts 3:19. See Jeremiah 3:12. God doth as it were bid them hearken to his messengers, and then he will heal their backsliding. I will heal your backslidings, i.e. idolatries, whereby you turned from me, and rebelled against me; I will take you into that state, as if you had never turned from me; I will make all whole again among you, and reconcile you to myself, Isaiah 57:18 Jeremiah 32:40. See Malachi 10:6, Malachi 13:9. I will not only remove your judgments, but your sins also shall be forgiven. Behold, we come unto thee. This is either God's framing their answer for them, prescribing the manner and form of their repentance, by a figure called mimesis, Hosea 14:2,3; or it is their reply to God by way of promise, which they performed under Josiah, 2Ki 22 2Ki 23, which with their confession reacheth to the end of the chapter. For thou art the Lord our God; words expressing the strongest inducements to it imaginable, because God hath right to them, is willing to accept them, and able to save them, Isaiah 55:7 Jeremiah 14:22.
