'Fast' in the Bible

“Go and assemble all the Jews who can be found in Susa and fast for me. Don’t eat or drink for three days, day or night. I and my female servants will also fast in the same way. After that, I will go to the king even if it is against the law. If I perish, I perish.”

Mordecai wrote in King Ahasuerus’s name and sealed the edicts with the royal signet ring. He sent the documents by mounted couriers, who rode fast horses bred from the royal racing mares.
