(17) Became Jews.--That is, embraced their religion as proselytes.

Verse 17. - A feast and a good day. The provincial Jews made the whole day on which they heard the news into a holiday, and not only rejoiced, but feasted. Many of the people of the land became Jews. Applied for and obtained admission into the Jewish nation as full proselytes (comp. Ezra 6:21, with the comment). The fear of the Jews fell upon them. There was about to be in each great city where there were Jews a day of straggle and bloodshed. The Jews would have authority on their side (Esther 9:3), and might be expected to be victorious. Persons feared lest, when victorious, they might revenge themselves on all who had not taken their part, and thought it safer to become Jews than remain neutral. But it can only have been a small minority of the population in each city that took this view. There was no sudden great increase in the numbers of the Jewish nation.

8:15-17 Mordecai's robes now were rich. These things are not worth notice, but as marks of the king's favour, and the fruit of God's favour to his church. It is well with a land, when ensigns of dignity are made the ornaments of serious piety. When the church prospers, many will join it, who will be shy of it when in trouble. When believers have rest, and walk in the fear of the Lord, and the comfort of the Holy Ghost, they will be multiplied. And the attempts of Satan to destroy the church, always tend to increase the number of true Christians.And in every province, and in every city, whithersoever the king's commandment and his decree came,.... As they did to every province in the realm, and to every city in the province, where there were any Jews:

the Jews had joy and gladness, a feast and a good day; they expressed their joy on this occasion by keeping a festival, which in their language is called a good day; and such an one is annually kept by them unto this day, on account of their deliverance; of which see Esther 9:27

and many of the people of the land became Jews; or were proselyted, as both the Targums and Jarchi interpret it; they embraced the Jewish religion, and submitted to the rites and ceremonies of it; were circumcised, as in the Septuagint version, and so were proselytes of righteousness; and indeed no other could they be, dwelling in their own land; many of them very probably were serious in it, observing the wonderful manner in which the Jews were delivered; wherein manifestly appeared to them the providence of God, the hand of the Supreme Being, and from hence concluded their God must be the true God, and they his favourite people, and their religion most correct; though others might only do it to gain the favour of Esther and Mordecai, who had now such great power and influence at court:

for the fear of the Jews fell upon them; lest they should be slain by them, in virtue of this new edict.
