Esth 9:28

“remembered with the reading of the Scroll [of Esther]. and celebrated feasting and rejoicing and a festive day, to give portions [of food to friends] and gifts [to the poor]. every family gather together and feast and drink together, and so they took upon themselves that the Purim days would not be revoked. shall not cease Heb. לֹא יָסוּף. This is the Aramaic translation of יִתֹּם, will end, for the Targum of (Deut. 2:14) “עַד תֹּם” is עַד דְסַף, until it finished, and it is impossible to say that it is derived from the same root as (Gen. 19:15): “lest you perish (תִּסָפֶה),” or from the same root as (I Sam. 27:1): “Now I shall perish (אֶסָפֶה) one day,” for if that were so, Scripture should have written: לֹא יִסָפֶה מִזַרְעָם.”

“And he sent letters unto all the Jews,.... That is, Mordecai did, signed in the queen's name, and his own: to the hundred twenty and seven provinces of the kingdom of Ahasuerus; among which was Judea, that was become a province, first of the Chaldean, now of the Persian empire, see Ezr 5:8 to whom also these letters were sent, directing and ordering the Jews there to observe these days, who were also concerned in the deliverance wrought: with words of peace and truth exhorting them to live in peace with one another, and their neighbours, and to constancy in the true religion; or wishing them all peace and prosperity in the most loving and sincere manner.”

“And that these days should be remembered and kept throughout every generation, every family, every province, and every city; and these days of Purim are not to pass away among the Jews, nor their remembrance to cease among their seed. The participles ונעשׂים נזכּרים still depend on להיות, Est 9:27. Not till the last clause does the construction change in להיות לא to the temp. finit. יעבור ולא is a periphrasis of the adverb: imperishably, inviolably. כּכתבם, secundum scriptum eorum, i.e., as Mordochai had written concerning them (Est 9:23). כּזמנּם, as he had appointed their time. מן סוּף, to come to an end from, i.e., to cease among their descendants.”
