Also in all and euery prouince, and in al and euery citie and place, where the Kings commandement and his decree came, there was ioy and gladnes to the Iewes, a feast and good day, and many of the people of the land became Iewes: for the feare of the Iewes fell vpon them.
Esther 8:15 And Mordecai went out from the King in royall apparell of blewe, and white, and with a great crowne of gold, and with a garment of fine linen and purple, and the citie of Shushan reioyced and was glad.
Esther 8:16 And vnto the Iewes was come light and ioy and gladnes, and honour.
Esther 8:17 Also in all and euery prouince, and in al and euery citie and place, where the Kings commandement and his decree came, there was ioy and gladnes to the Iewes, a feast and good day, and many of the people of the land became Iewes: for the feare of the Iewes fell vpon them.
The verse centers on "euery", "prouince", "citie", "place", "where", "kings", and "commandement". It is saying that the verse draws attention to "euery" and "prouince", so its meaning should be read from those terms before moving to application.
The prior verse says "And vnto the Iewes was come light...", giving immediate footing for "euery" and "prouince". In Esther context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "euery" and "prouince" with trust shaped by these words, not by a vague optimism outside the passage.
