Midrash for II Chronicles 36:23
כֹּה־אָמַ֞ר כּ֣וֹרֶשׁ ׀ מֶ֣לֶךְ פָּרַ֗ס כָּל־מַמְלְכ֤וֹת הָאָ֙רֶץ֙ נָ֣תַן לִ֗י יְהוָה֙ אֱלֹהֵ֣י הַשָּׁמַ֔יִם וְהֽוּא־פָקַ֤ד עָלַי֙ לִבְנֽוֹת־ל֣וֹ בַ֔יִת בִּירוּשָׁלִַ֖ם אֲשֶׁ֣ר בִּֽיהוּדָ֑ה מִֽי־בָכֶ֣ם מִכָּל־עַמּ֗וֹ יְהוָ֧ה אֱלֹהָ֛יו עִמּ֖וֹ וְיָֽעַל׃
’Thus saith Cyrus king of Persia: All the kingdoms of the earth hath the LORD, the God of heaven, given me; and He hath charged me to build Him a house in Jerusalem, which is in Judah. Whosoever there is among you of all His people—the LORD his God be with him—let him go up.’
Pirkei DeRabbi Eliezer
The seventh king was Cyrus, who ruled from one end of the world to the other, as it is said, "Thus saith Cyrus king of Persia, All the kingdoms of the earth hath the Lord, the God of heaven, given me" (2 Chron. 36:23). Ahasuerus ruled over half the world. Is not half the world but 116 provinces, as it is said, "This is Ahasuerus, who reigned from India unto Ethiopia" (Esth. 1:1).
