Even though you are still in the womb i'm choosing you to guide the nation
I'm scared to lead this big nation i'm only a young boy and have no experience
Do not fear as i'm with you and will guide you!
Bnei Yisrael Still did Avodah Zara and disrrepected Hashem even after all he did for them
"בְּטֶ֨רֶם אֶצָּרְךָ֚"-Hashem says that He picked Yermiyahu before he was even born
"Fear them not, for I am with you to save you, says the Lord." Hashem tells Yerhiyahu to not worry because He is with him and will guide him.
The sin of משובה ישראל
הָלֹ֡ךְ וְֽקָרָאתָ֩ בְּאָזְנֵי֙ יְרֽוּשָׁלִַ֜ם לֵאמֹ֗ר כֹּה אָמַ֣ר יְהֹוָ֔ה זָכַ֚רְתִּי לָךְ֙ חֶ֣סֶד נְעוּרַ֔יִךְ אַֽהֲבַ֖ת כְּלוּלֹתָ֑יִךְ לֶכְתֵּ֚ךְ אַֽחֲרַי֙ בַּמִּדְבָּ֔ר בְּאֶ֖רֶץ לֹ֥א זְרוּעָֽה-Hashem compares Himself and Bnei Yisrael to a married couple
Yehuda did not return to Hashem they went and did more avodah zarah, even though they saw what had become of Israel
לָ֥מָּה תָרִ֖יבוּ אֵלָ֑י כֻּלְּכֶ֛ם פְּשַׁעְתֶּ֥ם בִּ֖י נְאֻם־יְהֹוָֽה-Hashem talks about how Bnei Yisrael abanded him and did avodah zara
עָשְׂתָ֖ה מְשֻׁבָ֣ה יִשְׂרָאֵ֑ל הֹלְכָ֨ה הִ֜יא עַל־כָּל־הַ֣ר גָּבֹ֗הַּ וְאֶל־תַּ֛חַת כָּל־עֵ֥ץ רַעֲנָ֖ן וַתִּזְנִי־שָֽׁם׃“Have you seen what Rebel Israel did, going to every high mountain and under every leafy tree, and whoring there?”
Bnei Yisrael did Avodah Zara therefore destroying the land and making Hashem angry
וָאֵ֗רֶא כִּ֤י עַל־כָּל־אֹדוֹת֙ אֲשֶׁ֤ר נִֽאֲפָה֙ מְשֻׁבָ֣ה יִשְׂרָאֵ֔ל שִׁלַּחְתִּ֕יהָ וָאֶתֵּ֛ן אֶת־סֵ֥פֶר כְּרִיתֻתֶ֖יהָ אֵלֶ֑יהָ וְלֹ֨א יָֽרְאָ֜ה בֹּֽגֵדָ֤ה יְהוּדָה֙ אֲחוֹתָ֔הּ וַתֵּ֖לֶךְ וַתִּ֥זֶן גַּם־הִֽיא׃ “I noted: Because Rebel Israel had committed adultery, I cast her off and handed her a bill of divorce; yet her sister, Faithless Judah, was not afraid—and whored.”
