Reference for Joel 4:19

מִצְרַ֙יִם֙ לִשְׁמָמָ֣ה תִֽהְיֶ֔ה וֶאֱד֕וֹם לְמִדְבַּ֥ר שְׁמָמָ֖ה תִּֽהְיֶ֑ה מֵֽחֲמַס֙ בְּנֵ֣י יְהוּדָ֔ה אֲשֶׁר־שָׁפְכ֥וּ דָם־נָקִ֖יא בְּאַרְצָֽם׃

Egypt shall be a desolation, And Edom shall be a desolate wilderness, For the violence against the children of Judah, Because they have shed innocent blood in their land.
