Rabbi Shlomo Aviner in an interview to NRG-Judaism: “Render to the Academia the things that are Academia’s, and to Yeshiva the things that are Yeshiva’s“.
Sanity check: Jews don’t recognize the New Testament as holy scripture, and that’s when they are polite. R’ Aviner is one of the unofficial spiritual leaders of the “National Religious” movement, and even though he is a bit controversial inside his own milieu, he is not suspected of Christianity.
But then, in modern Hebrew there’s a common expression מלח הארץ – “salt of the earth”. I looked for its origin and the oldest that i could find was Matthew 5:13.
