It is conjectured that the prophet refers to a nuptial crown, Isaiah 61:10. But a crown, both on the bride and bridegroom, was common among most people on such occasions. The nuptial crown among the Greeks and Romans was only a chaplet or wreath of flowers.
In the day of the gladness of his heart - The day in which all his wishes were crowned, by being united to that female whom beyond all others he loved.
Here the third day is supposed to end.
