Esther 8:16

And the Jews had light
Prosperity, as opposed to the darkness of adversity in which they had been, see ( Isaiah 8:22 Isaiah 9:1 Isaiah 8:2 ) , or lightsomeness and cheerfulness of spirit, as explained by the two next words:

and gladness and joy;
at the good news of their deliverance, so unexpected by them; thus light is explained by gladness, ( Psalms 97:11 )

and honour:
among men; from their neighbours, who before were held in contempt, as a people doomed to destruction.
