The covenants
Abraham, Sinai, David, and the new covenant of Jeremiah 31: one story of God binding himself to Israel.
God promised Abraham land, descendants and blessing for all nations (Genesis 12, 15, 17). At Sinai he gave Israel the Torah (Exodus 19-24). To David he promised an everlasting throne (2 Samuel 7).
Through Jeremiah he promised a new covenant "with the house of Israel and with the house of Judah", with Torah written on the heart and sins forgiven (Jeremiah 31:31-34).
Yeshua said his blood was that new covenant (Luke 22:20). It doesn't cancel God's faithfulness to Israel: "the gifts and the calling of God are irrevocable" (Romans 11:29).
In the Scriptures
3וַאֲבָֽרֲכָה֙ מְבָ֣רְכֶ֔יךָ וּמְקַלֶּלְךָ֖ אָאֹ֑ר וְנִבְרְכ֣וּ בְךָ֔ כֹּ֖ל מִשְׁפְּחֹ֥ת הָאֲדָמָֽה׃
3And I will bless them that bless thee, and him that curseth thee will I curse; and in thee shall all the families of the earth be blessed.’
Genesis 12:3 (Hebrew & JPS 1917)
31הִנֵּ֛ה יָמִ֥ים בָּאִ֖ים נְאֻם־יְהוָ֑ה וְכָרַתִּ֗י אֶת־בֵּ֧ית יִשְׂרָאֵ֛ל וְאֶת־בֵּ֥ית יְהוּדָ֖ה בְּרִ֥ית חֲדָשָֽׁה׃ 32לֹ֣א כַבְּרִ֗ית אֲשֶׁ֤ר כָּרַ֨תִּי֙ אֶת־אֲבוֹתָ֔ם בְּיוֹם֙ הֶחֱזִיקִ֣י בְיָדָ֔ם לְהוֹצִיאָ֖ם מֵאֶ֖רֶץ מִצְרָ֑יִם אֲשֶׁר־הֵ֜מָּה הֵפֵ֣רוּ אֶת־בְּרִיתִ֗י וְאָנֹכִ֛י בָּעַ֥לְתִּי בָ֖ם נְאֻם־יְהוָֽה׃ 33כִּ֣י זֹ֣את הַבְּרִ֡ית אֲשֶׁ֣ר אֶכְרֹת֩ אֶת־בֵּ֨ית יִשְׂרָאֵ֜ל אַחֲרֵ֨י הַיָּמִ֤ים הָהֵם֙ נְאֻם־יְהוָ֔ה נָתַ֤תִּי אֶת־תּֽוֹרָתִי֙ בְּקִרְבָּ֔ם וְעַל־לִבָּ֖ם אֶכְתֲּבֶ֑נָּה וְהָיִ֤יתִי לָהֶם֙ לֵֽאלֹהִ֔ים וְהֵ֖מָּה יִֽהְיוּ־לִ֥י לְעָֽם׃ 34וְלֹ֧א יְלַמְּד֣וּ ע֗וֹד אִ֣ישׁ אֶת־רֵעֵ֜הוּ וְאִ֤ישׁ אֶת־אָחִיו֙ לֵאמֹ֔ר דְּע֖וּ אֶת־יְהוָ֑ה כִּֽי־כוּלָּם֩ יֵדְע֨וּ אוֹתִ֜י לְמִקְטַנָּ֤ם וְעַד־גְּדוֹלָם֙ נְאֻם־יְהוָ֔ה כִּ֤י אֶסְלַח֙ לַֽעֲוֺנָ֔ם וּלְחַטָּאתָ֖ם לֹ֥א אֶזְכָּר־עֽוֹד׃
31Behold, the days come, saith the LORD, that I will make a new covenant with the house of Israel, and with the house of Judah; 32not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; forasmuch as they broke My covenant, although I was a lord over them, saith the LORD. 33But this is the covenant that I will make with the house of Israel after those days, saith the LORD, I will put My law in their inward parts, and in their heart will I write it; and I will be their God, and they shall be My people; 34and they shall teach no more every man his neighbour, and every man his brother, saying: ‘Know the LORD’; for they shall all know Me, from the least of them unto the greatest of them, saith the LORD; for I will forgive their iniquity, and their sin will I remember no more.
