In those days I Daniel was mourning three full weeks:

I ate no pleasant bread, neither came flesh nor wine into my mouth, neither did I anoint myself at all, till three full weeks were fulfilled.

And now will I declare unto thee the truth. Behold, there shall stand up yet three kings in Persia; and the fourth shall enrich himself with great riches more than all; and when he hath become strong through his riches, he shall stir up all against the realm of Greece.

Blessed is he that waiteth, and cometh to the thousand three hundred and thirty-five days!
