Word of the Day / Tihye bari תִּהְיֶה בָּרִיא
It means "be well," except when it doesn't. As in, "You want to drive through that flood anyway? Good luck with that."
"Be healthy." It sounds like a nice enough phrase, a version of "be well" or "feel good." And sometimes tihye bari (tee-hee-YEH ba-REE, for a man) and tihyi bri'a (for a woman) are indeed used in that way, especially if the person on the receiving end of the phrase is sick or recovering from an illness.
