And Mordecai wrote these things, and sent letters unto all the Jews that [were] in all the provinces of the king Ahasuerus, [both] nigh and far,
Ver. 20. And Mordecai wrote these things] He wrote with authority, as a magistrate (say some), that the Jews should keep these days with greatest solemnity. He wrote the relation of these things mentioned before, say others, as the ground of this annual festivity. Or else it may be meant more generally that Mordecai was the penman of the Holy Ghost, in writing this whole Book of Esther, as was before hinted.
And sent letters unto all the Jews … both nigh and far] Propinquis et longinquis, near and far, that they might all agree together about the time and manner of praising God; and so sing the great Hallelujah. See 2 Corinthians 1:11 2Ch 20:26-28 Psalms 124:1,2; Psa 126:1 Psalms 136:1,26, penned for a recorded public form, to praise God among the multitude, Psalms 109:30, and in the great congregation, Psalms 22:22; Psalms 22:25. David would go into the presses of people, and there praise the Lord, Psalms 116:18,19. This was to walk worthy of the Lord, Colossians 1:10. This was to make a proportionable return, for we are God's soil, and our thanks his crop.
