Esther 4:14-16

For if thou altogether holdest thy peace at this time, then will relief and deliverance arise to the Jews from another place, but thou and thy father’s house will perish: and who knoweth whether thou art not come to the kingdom for such a time as this? Then Esther bade them return answer unto Mordecai, Go, gather together all the Jews that are present in Shushan, and fast ye for me, and neither eat nor drink three days, night or day: I also and my maidens will fast in like manner; and so will I go in unto the king, which is not according to the law: and if I perish, I perish.
