מדרש אויף ירמיהו 34:18

וְנָתַתִּ֣י אֶת־הָאֲנָשִׁ֗ים הָעֹֽבְרִים֙ אֶת־בְּרִתִ֔י אֲשֶׁ֤ר לֹֽא־הֵקִ֙ימוּ֙ אֶת־דִּבְרֵ֣י הַבְּרִ֔ית אֲשֶׁ֥ר כָּרְת֖וּ לְפָנָ֑י הָעֵ֙גֶל֙ אֲשֶׁ֣ר כָּרְת֣וּ לִשְׁנַ֔יִם וַיַּעַבְר֖וּ בֵּ֥ין בְּתָרָֽיו׃

און איך װעל געבן די מענטשן װאָס האָבן איבערגעטרעטן מײַן בונד. װאָס האָבן ניט מקיים געװען די װערטער פֿון דעם בונד װאָס זײ האָבן געשלאָסן פֿאַר מיר, בײַ דעם קאַלב װאָס זײ האָבן צעשניטן אין צװײַען, און זײַנען דורכגעגאַנגען צװישן זײַנע שטיקער –
