Ha’azinu makes צור “rock” a recurring name for God: הצור תמים פעלו, צור ישעתו, צור ילדך תשי. In modern Israel the epithet becomes a civil-religious formula: the 1948 Declaration of Independence closes ומתוך בטחון בצור ישראל, a phrase religious and secular signatories could each read their own way, and the Prayer for the State opens אבינו שבשמים, צור ישראל וגואלו. In everyday speech the physical “rock” is סלע; צור is literary/elevated, and צור ישראל is heard mainly as a national-liturgical name.

וַיֹּאכַל תְּנוּבֹת שָׂדָי: תנובה is the yield or produce of the land, a rare poetic noun. Zionist agricultural Hebrew adopted it as the name of Tnuva, the cooperative that marketed the produce of Jewish farms (founded 1926), and Otto Wallish’s mid-century posters made תנובה a household brand. The common noun still exists in elevated or technical register (“yield”), but for most Israeli speakers the word now first evokes the dairy company.

חמאת בקר וחלב צאן lists חמאה among the rich dairy of the land. Biblical חמאה is a cultured or curdled milk product that can be drunk: Yael, asked for water, gives Sisera milk, בספל אדירים הקריבה חמאה (Judges 5:25), and Abraham serves חמאה וחלב (Genesis 18:8). Modern Hebrew narrows חמאה to “butter,” the solid churned fat, as on Tnuva’s 1968 poster חמאה מלוחה (“salted butter”); other cultured milks get new names (לבן, יוגורט, שמנת).
