former, some on the latter day.
Verse 23
And the Jews undertook to do as they had begun, and as Mordochai had written to them. They had begun, as Est 9:22 tells us, by keeping both days, and Mordochai wrote to them that they should make this an annual custom. This they agreed to do in consequence of Mordochai's letters. The reason of their so doing is given in Est 9:24 and Est 9:25, and the name of this festival is explained, Est 9:26, by a brief recapitulation of the events which gave rise to it. Then follows, Est 9:26 and Est 9:27, another wordy statement of the fact, that it was by reason of this letter, and on account of what they had seen, i.e., experienced, that the annual celebration of this feast was instituted for a perpetual memorial to all Jews at all times (Est 9:28 and Est 9:29).

Verses 26-27
Wherefore they called these days Purim after the name Pur. This first על־כּן refers to what precedes and states the reason, resulting from what has just been mentioned, why this festival received the name of Purim. With the second על־כּן begins a new sentence which reaches to Est 9:28, and explains how it happened that these feast-days became a general observance with all Jews; namely, that because of all the words of this letter (of Mordochai, Est 9:20), and of what they had seen concerning the matter (על־כּכה, concerning so and so), and what had come upon them (therefore for two reasons: (1) because of the written injunction of Mordochai; and (2) because they had themselves experienced this event), the Jews established, and took upon themselves, their descendants, and all who should join
