'Day After Day' in the Bible

Now it happened when they had spoken to him day after day and he would not listen to them, that they told Haman to see whether Mordecai’s reason [for his behavior] would stand [as valid]; for he had told them that he was a Jew.

In the first month, the month of Nisan (Mar-Apr), in the twelfth year of King Ahasuerus, Haman cast Pur, that is, the lot, cast before him day after day [to find a lucky day to approach the king], month after month, until the twelfth month, the month of Adar (Feb-Mar).
