Jeremiah 50:11 Midrash

כִּ֤י תשמחי [תִשְׂמְחוּ֙] כִּ֣י תעלזי [תַֽעֲלְז֔וּ] שֹׁסֵ֖י נַחֲלָתִ֑י כִּ֤י תפושי [תָפ֙וּשׁוּ֙] כְּעֶגְלָ֣ה דָשָׁ֔ה ותצהלי [וְתִצְהֲל֖וּ] כָּאֲבִּרִֽים׃

Because ye are glad, because ye rejoice, O ye that plunder My heritage, Because ye gambol as a heifer at grass, And neigh as strong horses;
