C. F. Keil and Franz Delitzsch on Esther 9:18-19

Est 9:18-19

The Jews in Susa, on the other hand, who were both on the 13th and 14th Adar still fighting against their enemies, and did not rest till the 15th, made this latter their day of rejoicing. - In Est 9:19 it is again stated that the Jews in the country towns and villages made the 14th their day of gladness, and this statement is appended by על־כּן to make this appear the result of what precedes. The Chethiv הפּרוזים is perhaps an Aramaic expression for פּרזים, Deu 3:5 and 1Sa 6:18. פּרוזי means the inhabitants of the open, i.e., unfortified, towns and villages of the plains in contrast to the fortified capital; see on Deu 3:5. On פּרזות, compare Eze 38:11; Zec 2:8. וגו מנות משׁלוח, and of mutual sending of gifts, i.e., portions of food; comp. Neh 8:10, Neh 8:12.
