פְּרֵ֑ס פְּרִיסַת֙ מַלְכוּתָ֔ךְ וִיהִיבַ֖ת לְמָדַ֥י וּפָרָֽס׃
ПЕРЕС, царство твое разделено и дано мидянам и персам.'
Rashi on Daniel
Your kingdom has been broken up, etc. i.e., UFARSIN means two definitions of PEREIS; one is that your kingdom פְּרִיסַת, your kingdom has been broken up, and the second one is that it has been given to Media and Persia (וּפָּרַס).
