A za dni Artakserksesa pisał Biszlam, Mithredath, Tabeel i resztę swoich towarzyszy do Artakserksesa, króla perskiego; a pisanie listu zostało zapisane po aramejsku i przedstawione w języku aramejskim.
Rashi on Ezra
And in the days of Artaxerxes He is Cyrus, the king of Persia. The numerical value of the letters of כּרֶשּׁ equal the numerical value of the letters of דָּרְיָוֶשּׁ: [כ = 20; ר = 200; שּׁ = 300; total = 520. ד = 4; ר = 200; י = 10; 520 ו = 6; שּׁ = 300; total = 520.] And so we learned in Tractate Rosh Hashanah (3b): “The same one is Cyrus, who is Darius, who is Artaxerxes.” [He was called Cyrus כּרֶשּׁ because he was a worthy (כָּשֵּׁר) king; Artaxerxes, because of the kingdom, and in Seder Olam (ch. 30): “Darius was Artaxerxes (אַרְתַּחְשַּׁשְּׁתָּא), and the entire kingdom was called Artaxerxes, etc.” [meaning that all the kings were called Artaxerxes].
