What does 2 Chronicles 30:9 mean?

If you come back to the Lord, your relatives and children who were taken away will find compassion from those who captured them, and they’ll be allowed to come home. The Lord your God is kind and caring. If you turn back to him, he won’t turn his back on you. 2 Chronicles 30:9 - Modern Text Bible

(Hezekiah promises that God’s mercy extends even to those in exile. If the people return to God, he’ll show kindness and restore their families.)
