Jeremiah 3:9

"And the faithless Judah did not fear, and she went and played the harlot herself also." Israel having played the harlot first, Judah too played the harlot afterward. "And her fornication became as nothing, and she committed adultery with wood and stone." Whenever we sin, we do nothing else than, becoming stony-hearted, commit adultery with "the stone." Whenever we sin and play the harlot "beneath every leafy tree," we too commit adultery with "the wood." "And the faithless Judah did not turn to me with her whole heart, but in falsehood."

Those who place themselves far from your care and choose to serve idols will reap the destructive fruit of defection. He calls idolatry infidelity here. God likewise says also through Jeremiah, "She went up every high hill and under every green tree and was unfaithful …

Let us now proceed to consider the mode of his loving discipline, with the aid of the prophetic testimony. Admonition, then, is loving care's censure and produces understanding. Such is Christ the Educator in his admonitions, as when he says in the Gospel, "How often would I have gathered your children, as a bird gathers her young ones under her wings, and you did not allow it!" And again, the Scripture admonishes, saying, "And they committed adultery with wood and stone and burned incense to Baal." For it is a very great proof of his love, that, though knowing well the shamelessness of the people who had kicked and bounded away, he notwithstanding exhorts them to repentance and says by Ezekiel, "Son of man, you live in the midst of scorpions; nevertheless, speak to them, if perhaps they will hear."

(Verse 6 and following) And the Lord said to me in the days of King Josiah: Have you seen what the adulteress Israel has done? She went upon every high hill and under every leafy tree and committed adultery there. And I said, after she had done all these things: Return to me, but she did not return. And her treacherous sister Judah saw that I had dismissed the adulteress Israel and had given her a bill of divorce. But her treacherous sister Judah did not fear, but she also went and committed adultery.

Admonition, then, is loving care's censure and produces understanding. Such is Christ the Educator in his admonitions, as when he says in the Gospel, "How often would I have gathered your children, as a bird gathers her young ones under her wings, and you would not!" And again, the Scripture admonishes, saying, "And they committed adultery with stock and stone and burned incense to Baal." For it is a very great proof of God's love that, though knowing well the shamelessness of the people who had kicked and bounded away, he nevertheless exhorts them to repentance. He says by Ezekiel, "Son of man, you dwell in the midst of scorpions. Nevertheless, speak to them, if by chance they will hear." Further, to Moses he says, "Go and tell Pharaoh to send my people forth, but I know that he will not send them forth."
