In Hebrew you say "Shalom" for piece.
The People of Israel = Am Yisra'el (עם ישראל)
There are many way to say this, but k'hillat Yisrael (קהילת ישראל) would be the most literal.
in Hebrew you say kesef (כסף)
"YEES-rah-EHL"
"He mitga'agaat le Israel" (היא מתגעגעת לישראל). And don't worry about the 'he' part, in Hebrew 'he' means 'she'.
Kehilla
It's Hebrew and refers to a collective farm or community in Israel.
The official name in Hebrew is "Medinat Yisrael," the State of Israel in English. Medina in Hebrew is an older word previously referring to a national community and the Zionist Jews forming Israel felt that it would be a perfect double entendre to use it as the name of the country. It could be read literally as "The State of Israel" or it could be read as "The National Community of the People Israel". This would signal to other Jews the historic nature that Israel represented the culture and future of the Jewish people, unlike any other modern country.
goodbye in Hebrew "Le'Hit'Ra'Ot".
There is nothing called Israellanguage. In Israel you talk Hebrew or Arabic.
