Albert Barnes Commentary Jeremiah 3:22

"Return, ye backsliding children, I will heal your backslidings. Behold, we are come unto thee; for thou art Jehovah our God." — Jeremiah 3:22 (ASV)

Yahweh’s answer to their prayer in (Jeremiah 3:21) is immediately followed by their acceptance of the offer of divine mercy.

For - Rather, because... This profession of faith gives the reason why they return to Yahweh.

The whole description is most vividly depicted. The people weeping upon the hills: God’s gracious voice calling them to return: the glad cry of the penitents exclaiming that they come: the profession of faith won from them by the divine love; these together form a most touching picture of a national repentance.
